thanks for your help everyone, please add any info you might have while im still kinda in the dark as to what to do after the TCA.

 

remove everything and go full non-sequential

 

no i dont think ill be doing that...

 

Thats the whole point, we already knew his boost pattern, its not the problem. Putting the car on a dyno will allow him to see whats really going on. Hell, if you know someone with a datalogit and a wideband, go out and do some logging, that should lead you down the right path. I have been working on these cars for a long time and anytime you get a problem like this, it always seems to be a fuel issue. If your reading a positive manifold pressure and not the subsiquent power, the only option is and overly rich mixture or ignition problem. If he was overly lean, he would be seeing more power and detonation, but hes not. If he was seeing an ignition problem, he would more than likely be seeing it up top, not down low where the stock ignition system is more than adequate.

Put the car on a friggin dyno and watch the ratios, I would bet money you have a wet spot right were you loosing power.

C'mon Steve, jump in and back me up on this. Have all the people that know what they're talking about left this forum?

 

He doesn't have a boost problem.

 

Take it to a shop with a dyno, bring the sheet back here, post it on the forum and ask for advice.

 

Have you talked to the person who tuned your car? Was it tuned?

 

I'd like to know how you knew that seeing as it appears you're in Austin, he's in Fla, and the actual boost pattern wasn't written to the thread until later. Actually I don't need to know, because the point is that the issue hadn't been closed. But now it is, and I'll bow out since I know jack about tuning and ignition issues.

Was Tuned At Pettit And Is Dumpinh Fuel In The Mid Range And Killing The Spark Basically, Why? Well We Could Not Figure That Out....
