Now I know I'm gonna hear it anyways but I'll say it right up front...I'm running the 2.4" pulley. Also running a CAI, TR-55'* gapped to .050, 180º drilled T-stat. Now we're @ 112k miles. Here comes the problem....
Car runs superb when in open loop, meaning no bouncy idle, AT ALL, throttle body and MAF have just recently been cleaned last week. Under WOT she PULLS HARD and strong all the way up to the speed limiter, Boost pegged at 11 psi or more. Now once in closed loop, WOT runs are limited for me. She won't let me do it. IT almost feels like the fuel pump is backing off or the car'* starving for fuel. But upon initial pedal mashing (doen't matter what speed I'm going) she'll release some spark knock, and then loose all kinds of power (the kind you feel when a cylinder is not firing). But everything is fine until boost gets up over 7-8 psi (which is now no longer WOT).
Where do I start? Plugs and wires are new about 10-15k ago. Fuel pump? Maybe. Any chance the O2 sensor is not able to keep up with the extra boost? I was leaning more towards this becasue my problem is only there in closed loop (Warmed up). Actually let me take that back. Doesn't the PCM go back to open loop during WOT? But I was thinking fuel pump too as it might be loosing efficiency when IT warms up too, dunno. I don't have 24hr access to the Tech II so I can't get her on there to check for any Lean or Rich codes. I do have my MIL on but it'* because I have the EGR unplugged (runs better without it - see this post http://www.bonnevilleclub.com/forum/...883&highlight=
for htat reason. I know this EGR problem isn't the cause of my WOT problems either. And if it matters, I was getting this spark knock on a WOT attempt even when the car was stock with stock wires plugs, etc.
Someone...please...HELP! I need WOT power after my car is warmed up.
