manny, yes I'll install the cooler as soon as I find a suitable one but thats hard since it's very cramped in the engine bay
super SEC, your advice was of great help to me! At first the car was running very lean and under boost the ECU would switch to closed loop mode (the reading form the O2 would always stay on 0.44 like when the O2 is broken), after I enriched it in the way you said the car runs fine, the O2 now registers 0.91 - 0.93 volts under full boost (is it not to rich now, should I set it to read about 0.8 - 0.85 ??). The car now drives great, it has a great pickup from 2500 - 5000 rpm, but above that it seem to straggle and it is very hard to get to 7000 rpm (it used to rev with no hesitation to 7200 before), fuel is not the problem the O2 registers above 0.9 volts (I have the volt meter tied directly to the O2 wire). Any suggestion on where I should look for the problem ??
P.S. Can any one advise me on what diameter intake (from turbo to throttlebody) and exhaust pipes I should use ?
