Case Study: Road "Tuning" vs Dyno Tuning (Merged)

...and the drama begins once again.
Why don't we end this BS drama "I can tune better than you" by having all the top tuners willing to participate in the country TUNE THE SAME CAR. Is this what it has come too?
Nascar teams have engine build offs, why can't we have tune offs? I'm calling the Speed Channel first thing in the morning to set this up.

The good thing is that this customer ended up with what looks like a haulin' *** IX with no issues.
The bad thing is the alluding to Buschur's staged parts as not being useful or good mods when there are countless cars out there with these mods who post great dyno numbers as well as great numbers at the track. I personally don't care for intakes, but the intake in question here is not a Buschur product anyway.

BTW - the car was tuned originally with ecutek
I will post the data logs tomorrow which show the car holding the same boost level as shiv's tune after I tuned it and it was obviously makinga lot more power

Statix (Gabe),
Please, correct me if I'm wrong. But your drivability issues could have been easily addressed had you ever given Vishnu the opportunity. You told me that your main concern was that your car with the BR500 was stall prone with the Xede. I'm assuming that is the drivability issue you are referring to. Tons of us run turbo upgrades with the Xede without stalling issues. Above, Shiv is referring to a reflash, not his Xede piggyback.
However, correct me if I am wrong (seriously), but your car ran a 12.0 at 118mph with the Xede and made nearly 400whp on Shiv's dyno with that really bad BR500 that has long been discontinued. Your car never ran that fast with Al's reflash. I know, because I followed your progress like a hawk as IE Evo and I saw you as a friendly competitor.
I'm kinda surprised to see you in this thread. In fact, your loyalty to Al and DB honestly confounds me. I know for a fact theadditional following things about your car:
1. You had Buschur Racing's full stage 4 with a custom race fuel tune by Al and did a best of 12.6 at 109mph at California Speedway while IE Evo and I were both running consistent 12.3 at 112 with our completely stock looking Vishnu 1+s. Next you went big, getting Buschur's brand new BR500.
2. After getting rid of your unresponsive BR500, you opted for the BR440. Unfortunately, it came up a little short on power (375whp on a race gas tune on a dynojet). You explained that it could have been due to the BR cast exhaust manifold coming loose again. You (and several others on this forum) said that the bolts repeatedly worked themselves out and the turbo would come loose.
3. Next, you went back to a stock turbo and bought one of the ill fated Buschur/Dynoflash SMC alky kits with the bad circuit boards. It malfunctioned and it blew up your motor. David Buschur acknowleged that SMC screwed up and you said he helped you by selling you one of his stroker motors at a discount. However, Al just recently bashed you and blamed you for blowing up your motor.
4. Now, according to you, that Stroker motor, done by Buschur, uses a quart of oil at almost every other tank of gas.
But, you get on this thread about reflashes and go negative on Shiv?
Gabe, I like you and have always enjoyed your company but I just don't get how you can stay loyal after so many bad experiences.

Almost all your gains in power came from increased boost levels.
And please stop making excuses until you completely absorb the entire post, graphs and all.It's also "fairly idiotic" to claim that the 55-60lb-ft of torque difference between the two tunes at 4400rpm is caused the one extra psi more boost my custom tune runs. Must be my "moon dyno", right?

Maybe your brain washed followers will grasp the comparision between 17 psi and 21 psi of boost in the heart of the power band - however more open minded readers will surely realize that 3 - 3.5 psi of extra boost will in most cases = more power ion fact significantly more power
BTW - here is the data log of how the car was tuned when I tuned it
The boost was hiting 20.5 psi and tapering to just under 19 psi
As shown the a/f is a razor smooth 10.89 across the board and the G force shows the car pulling smoothly and rather smartly.
When I drove the car it was without a doubt the fastest Evo I have driven on stock cams with 91 octane.
I am 100% sure a boost leak developed after I tuned the car
The customer was very displeased with the sound of the BOV as heard through the Buschur intake and commented that he did not like the sound - but ANY open air intake will allow the owner to hear that same sound when you release the gas and the air is heard venting back into the intake
I have seen a handful of customers who were disatified with that sound but time and time again it has been shown that the removal of the stock air box yields additional power
I think you will have a hard time convincing the members here that Buschur Racing staged kits need to be "removed" to resore the car to normal operation
I have found many happy Buschur customers
All i wall add is that the results at the race tracks across the USA by dozens of Buschur Customers vs. Vishnu customers prove that your products are slow in comparision and make little power for a lot of money
I am sure that many users will agree that compared to your overpriced goods the Buschur Products offer huge bang for the buck and high quality
I will leave it to Mr. Buschur personally to respond further to your very unprofessional and moronic attacks upon his fine products and excelent reputation
Here is the data log showing that wehen the car was in my hands it was holding excelent boost
I have to teach you how to diagnose and correct boost leaks when I am back out your way

What about cars that are tuned using a Dynojet vs a Dyno Dynamics dyno? I have always been accustomed to using a DD dyno back when my cars were in Australia. Most of the available dynos here are all dynojets. I feel a significant difference in tune and performance of the car tuned on a dynojet and on a DD dyno. Perhaps you can quantify the differences and why in effect a car will run so different at the track after the tune??

#1 I did not post here to flame anyone nor support either, just stating the facts.
Stalling of my car was the main concern but not the only one.
Taking the car back to Shiv is a 12 hr round trip drive.
There is no longer any loyalty to Al or DB again my car did run best(maybe not the fastest) with Al flash, just because I may or may not like the guy anymore mean that Im going to go around and spread lies.
As far as times go, You and I both know for what ever reasons I was having cronic 3rd to 4th gear grinds, which hindered me extremely.
My very last run with my new ACT clutch yielded my a 1.7 60ft on a slip, which if my motor didnt nuke it would have been a good run, not the mention the guy I was racing was the guy from vegas that beat you that same night, which I was killing by about 3-4 cars before you know...
For the BR 440, I could only run 24 psi with a major boost leak, If I could have I would have run 28-30 without any leaks, but we know how that goes.
For awhile my stroker motor was using a lot of oil, maybe everything needed time to seat for my oil consumption is near stock at this time.
Wow, so go back to my post and realize that I was not bashing anyone, only stating the facts, it is the truth weather I like Al, Shiv or DB.
Me and Al have had are words and I no longer do busines with him.
So, back to my main point, My road tunes ALWAYS come out better than any of my dyno tunes( and I have had several).
So when's the 91 pisstane shootout, I think it time for some more good ol competition
BTW: its almost scary how of my cars past you know, I think you remember more than me, it may not all be accurate by close enough...
