Member BBYBruno was custom tuned at Buschur during my dyno day back in June of 2006

Recently - all heck broke loose on the forums after Bruno was not happy with his performance

Here is SOME of what he recently had to say


Sadly when Bruno "validated" his results his car actaully slowed down by 1 mph

I was shocked to hear of Burno's problems as I had not heard from him and when I tuned his car back in June it was totally knock free and smooth - producing a very nice looking dyno sheet

David Buschur wisely stated last week

I can also assure you of something else. IF the car was actually knocking after Al did a custom tune on it when it was here THEN SOMETHING CHANGED SINCE THEN. NO doubt in my mind. Whether it was octane, boost, parts combination or something else, something changed.


Suffica to say I was some what dismayed to hear of the customer's troubles and offered to re-check / re-tune his car for free so that I could personally find out what his problem was

Today BBYbruno brought his car in and I asked Dan Buschur to test the copmpression, do a boost leak test, and check the cam timing

The engine checked out perfect on compression and cam timing but it had a nasty boost leak behind the manifold

Also a large vacum nipple was missing on the inatke tune

Speaking of the intake tube it was a Weapon R type which has a inner tune within a tube style which in David Buschur and I's opinion is overy restrictive. Rather than deal with an unkown and obviously flawed product we suggested that the customer which to a stock intake tube combined with the weapon R filter assembly.

Now - with the boost leaks fixed and a proper intake tune it was time to take to the dyno and see how this car was performing

Frankly, this particular car was very knock happy. In order to get it to run smooth on the knock counts it required a significant amount of retarding of timing and enrichment, but after some balancing of tuning parameters a decent balance between power and knock was achived.

Then it was time to "test" his 100 octane "racing fuel" obtained at the gas pump at a local Speedway gas station.

Introducing the 100 octane fuel immediately resulted in INCREASED knock counts and the car began exhibiting terrible detonation

Thereafter, 5 gallons of C16 race fuel from a sealed VP barrel where mixed with his 5 gallons of pump gas and 100 octane mix to produce 10 gallons of mixed fuel

At that point his knock situation was significantly aleviated and normal tuning could proceed

Nomal tuning parametres achived a normally expected dyno power delivery at this point although even with the C16 the car was still able to knock if it was pushed which confirms that the 100 octane "racing" fuel was of extremely poor quality and very detonation prone

Customers should be aware that ANY fuel pumped out of a ground tank is subject to contamination, and there is no way to prove the honesty of the gas vendor or its suppliers.

It is for this reason that I persaonally always prefer to secure my race fuels from sealed containers so that the fuel is known to be pure and unmolested.

Please review this article for additional information :


Finally - to wrap up the test and have a "control" of some sort to rule out any other unkown factors on my last car of the day . . . . . I tuned it to the point where the tune was right on the edge of his pump gas at 22 psi and exhibiting 1 - 2 knock counts on spool up

This was a totally seperate car with similar Stage III mods

We took 2.5 gallons of the 100 octane "race" fuel and added it into the test subject vehicle's gas tank with NO OTHER CHANGES what so ever of any kind

We did ONE pull before adding the 100 octane fuel

Here are the knock counts and timing

Thereafter - we did one pull with the 100 octane "race" fuel - same tune - same boost - same collant temps - ONLY change is adding the 2.5 gallons of fuel on his 1/8th tank of 94 octane pump gas

The results are dramatic

The car is knocking so badly it is throwing off the dyno and can be heard as a loud marble sound in the block - nasty fuel - about the worst I have ever seen

I think I have demonstrated the following in this case study

1 - All cars need regular boost leak tests

2 - Fuel quality varys and must be carfeully considered

3 - When fuel quality suffers knock counts go up

4 - Often there is more to a situation that simply blaming the tuner

Thanks to Bruno for comming abck to have his car tested and thanks to all the customers who's appointmenst were delayed while I was messing with Bruno's car

Al

 

you tuned the car, not dave. we're more interested in "your" opinion

 

Damn, late night Al? lol SlowCar read the last sentence And thanks for the good work Al, the ride home was a lot of fun!

 

Only a irrational and hard headed individual such as yourself would not be interested in the opinion of one of the world's leading 4G63 experts

 

As the world's leading "stock ecu flasher", i'm sure you got your own opinion w/o always dragging dave into everything?

 

I can feel the heat from this thread

 

Its nice when you have the world's leading 4G63 expert on hand to render a opinion and observation

it just so happens that this car was tuned both times on Buschur's dyno so its nice to have a 3rd parties imput

 

Dynoflash took care of his customer . End of story , good work AL

 

Good job Al, let's hope Mr. Bruno posts and is happy.

 

still a little butt hurt are we Al.... I read the other thread... I never took it as anyone was basking you or your tunes... So why take offense... Why post this thread to redeem yourself when there is nothing to redeem... Your being extremely childish...

 

Come on. Your know the answer. How about being honest concerning your issues with Dynoflash? You follow him all over the site posting skeptical questions and statements. You really don't have an interest other than "tricking or catching" Al making an incorrect statement. Am I wrong?

If you have issues with a specific vendor please forward them to any moderator. The information will be passed to the owner for review. There is no need for you to clog every thread with questions you have no interest being answered. At least be honest relative to your own agenda. Thanks.

Frankly, when I see a car that is not working properly or has some problem I see it as an oportunity to learn and expand my skills

Often cars can be complicated to sort out and the more experience you have resolving these kind of problems the better you get at figuring this stuff out

I knew in my heart that some simple problem lied at the root of Bruno's situation - I guess I just wanted to have the specific details staight for my own personal growth and satisfaction

I take a LOT of pride in what I do and try to go above and beyond to stand behind my services

 

Many negative things were said about Al in the previous thread and you know what? He proved that the car did have mechanical issues, the 100 octane was of poor quality, and that he does stand behind his work. All the naysayers have been proven wrong again IMO. Great job again!!

 

Al I disagree with your statement there. My appointment was at 12pm. I actually got on the dyno around 2ish because the first guy (10 or 11am) was late and thats were it all started from.

So don't make it seem like everyone was waiting on me. There was actually that white evo that we waited on getting an uicp, bov, & mini battery installed.

Thats besides the point. I'm defenitely happy with the outcome yesterday. We got the boost leak fixed and found out the "100oct" gas was ****. I did put down some more power then before (updated in my sig) so of course happy with that.

The intake swap really did nothing. I had the Weapon-R Secret Weapon intake. It has another smaller tube inside the intake pipe which creates more velocity into the turbo (about 3x more) this is from the testing they performed. Any one can take a look at there write-up on weapon-r.com before you start speaking negatively about the intake. So Al made be buy a stock intake ($50), later on he told me "I guess I really didn't do much" So swapping out to stock did not increase hp/tp like he said.

So anyway i'de like to thank Al for re-tuning me and paying for the boost leak test, compression test, and cam timing. I couldn't be happier.

And thanks to Buschur for letting me come back to his shop even though he really didn't want me there.

I'll be back again once I get the rest of my mods and the new 20-g

 

I am as of yet still NOT ABLE to make a deifnitive conclusion about the Weapon R intake

The reason why was last time your 100 octane was good and the tune had more snap to it

This time although we swapped intake tubes the timing is signicantly lower than last time

I would catagorize the results as - you are making more power with a less agressive / more conservative tune

In order to effectively test the Weapon R intake tube (which you left at Buschur) you would need to do a A - B test back to back - same car same dyno same tune etc

Please PM me your email so I can forward your pump gas tune
