Weird problem. I'm running about 20lbs of boost on a T51 turbo. 42lb injectors with super fuel pump, cold air intake...blah blah blah. Got my fuel pressure static set at about 36-38 lbs, getting O2s of like 820 at WOT. From looking at my ET slips, it seems that my car accelerating low end good, but when it hits the high end, I am peaking at around 98mph. Gearing is good and all that, so no need to bring it up. I'm wondering if this may be an air problem - if there is an upgrade that I should do, or if I should keep dropping fuel pressure. I'm not getting any retardation. The chip I have is fairly low timing. Let me know what you gents think.
Without knowing anything further of your car:
Get rid of the catalytic converter.
Could need valve springs.
Is the motor knocking?
Where is the valid data?
You DO have a scantool, don't you?
I have a 3" high flow cat. Should that be enough? I'd like to keep the car legal if possible.
Any other signs that I may need valve springs? Something to look for?
No motor knock.
What do you mean by valid data? And yes I have a scantool. It gave me my O2 voltage.
