So as you have read in my previous threads, I am having boost issues. I shortened the waste gate for a tighter seal and that mainly fixed part of the issue. Here is what is happening now.... Its an automatic A413 tranny. The ECU is stage 3 FWD performance, set to 15 PSI. In DRIVE the car has no power from dead stop to WOT, feels almost as if it is in 3rd gear right off the bat. In GEAR 1 at a dead stop to WOT once it reaches 4000RPM I get 11 PSI then I shift to second gear and get around 5-7PSI then I shift to D and get maybe 2 PSI. But in D it doesn't downshift...very odd right? Are these trannys by any chance really picky when it comes to fluid? Could that be an issue?
I did a compression test and fuel pressure test, both passed. A/F ratio is good.
Could the waste gate solenoid be faulty since its only holding 10psi but ecu is set to 15?
ANY HELP IS APPRECIATED THANK YOU!
