Re: Tuning Problems.
I would change out the mass air meter for a 90. I have seen the cams be a little off from the factory causing some cars to make less than normal also.

Re: Tuning Problems.
Could the flattened curves and low power be indicative of a clogged catalytic converter?

Re: Tuning Problems.
if it cant get the exhaust out, its defintely a possibility. You may try running a can of seafoam through the engine to clean it and the cats out. Do a search, i believe we have discussed it before on here.
Also, whens the last time your fuel filter has been changed?

I replaced the fuel filter when I installed the fuel pump ( right before Thanksgiving). |

Re: Tuning Problems.
I've heard of cars leaving the factory with the carpet in the way of the gas pedal or something and not being able to truly achieve WOT.

I checked that when I installed the new plenum and throttle body. I think I'm going to try swapping the x-pipe with an off road x that I borrowed from a friend to see if I might have a clogged cat. Sometimes I can smell something eminating from that general area. |

Re: Tuning Problems.
Well the cats seem to be flowing fine. I had a pressure test done on the cats. It showed no blockage. Anyone have any other ideas?

Re: Tuning Problems.
I spoke with the tuner again. He mentioned that the 2003 GT that this tune was originally made for, achieved 180% load while mine only achived 140%. Both cars achieved 10 psi of boost at 5700 RPM. What would make the load be so different? The 2003 GT did have the later style MAF with the bar only protruding half way into the flow, while mine is the older style with the bar all the way across the meter. Is there a difference in the way these two meters read other than the newer stlye having the temperature sensor integrated into the meter?
