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

I'd even bet that it would cause the MAS to behave a little eraticly. Thoughts?
1) Al usually crushes the 1G when he tunes cars that have it, and
2) If they switched back to the stock BOV, then it would have been as weak, if not weaker than the 1G.
So, unless the 1G happened to fall apart internally between the road tune and the dyno tune, then I don't think it's a point of concern.

How would a tuner know that a BOV is leaking(assume it hooked up to recirc)? What are the tale-tale signs?

It is always possible that the car may have been in limp mode when it was originally tested
I am only suggesting a boost leak as there is no way the car falls 3 psi of boost lower than when I tuned it without some mechanical issue arsing
I have tuned more evos than anyone and my tunes do not have 35 - 40 less tq than whp - just not the way it comes out unless there is some mechanical defect
Rather than leaving all parts in place and changing the tune - SHIV elected to change the parts and the tune first so we will never really know just what the cause of the condition was

What may have worked well for an Evo VIII does not carry over well to the IX. Boost alone cannot account for that much mid range power.

Limp mode? More EVO tunes than anyone? Highest WHP of any EVO IX? Massive Boost on 91oct? The list goes on....

OK it seems that Shiv is NOT interested in taking the car to a dyno to have his work tested and verified to see how that high boost is faring and how much timing is now being pulled
Secondly - it seems he is not interested in having me re-install the parts and verify that all mechanical aspects of boost are correct and re-tuning the car
It seems that you ARM CHAIR quarterbacks would rather pontificate and speculate about theory and fantasy
I am not going to waste any more time with you guys - it seems reality and facts have little import
Just for my two cents . . . . . . .
The car came in with some unspecified problem - (I diagnose a boost leak) - however its pure conjecture. I road tuned the car and did 20 or so passes and the boost was holding well through the end of the pulls at 7800 rpms
(An aside - I do not log rpms in a Evo IX at this point as I am having a harness built to do that function as I have on the Evo 8) You can tell it was a full pull by the seconds it took to go through 3rd gear which remains fairly constant from car to car with similar mods. The boost was not falling down significantly.
Anyone who has a Stage II car knows you dont run them with a MBC falling to 16 psi of boost and if it is falling to 16 psi of boost and it was tuned fror 19 psi that is going to throw off the tune
Furthermore - the condition causing the boost leak would also have a negative effect on power - possible resulting in greater back pressure and knock as the wastegate would be 100% closed at all times
These are all basic theories of tuning but in your hatred and jealousy against me you are blinded to reality in any possible opportunity to bash me and prove Shiv is the better tuner
The way to test a tune - leave all parts alone - change the tune - then you have a A- B comparsion
By changing the parts on the car and then testing you may have corrected the problem which was the main root of the defect
Of course comming from a vendor so filled with hatred and negative toxic motivations towards me that he would waste his time offering $25 dyno sessions to lure in more people to test under these highly unproessional conditions I would expect nothing less than a totally scewed result
You wont see me offering any reduced price services to test the cars tuned by others tuners as at least 50% of my customers here on any given day are already here after having tried out some other tuning product - its not a big deal
My business is tstrong enough I dont have to waste my time to attack others - the customers already know who is doing what
For those who have drawn the conclusion that the results of this stunt reveal that Shiv has some secret MIVEC methods - you are very deluded
Thanks and carry on - I guess me and David wont be going to CA after all

Where did I say that I'm not interested in what you and Dave are proposing? Seriously Al, you need help.-shiv
PS. Are we going to bear witness to the now famous Dynoflash rant where you do 6-10 posts in a row, each one more outlandish than the previous one?

I am going to forward my tuning files to Merv at Ecutek in the Uk from this car along with my flashevo.log data and ask him to render an opinion on the quality of my tuning on this car as it was a Ecutek product and I am mereley a dealer as are you. Rather than play games with you who is obviously biased and trying to promote yourself at others expense I will let Ecutek handle this matter going forward as they are obviously in a better position to review the maps and make a decsion about what if anything was wrong with my tuning.
