GIAC ecu installed

**2BblkAudis** · 10-04-2008 06:35 PM

I just got a GIAC flashed M-box and installed it in the car. The ecu has stock, pump and race. The pump program is the 93 octane program, so i filled the tank with a mix of 91 octane and 100 octane to get an approximate 94 octane mixture. After filling up, I switched to the pump program and drove conservatively for about 30 miles. After that I started to give it some more gas and started boosting a little more. The question I have is that the car spikes at 22 psi and easily pushes 20 psi. The problem I'm having is that intermittently the car will sputter for a little bit then start boosting again. Its almost as if the car is not getting fueling or something. Anyone have any idea what's going on?

Thanks!

Stage 1 chip should not be spiking or coming anywhere near 22 psi. Somethings up.

Damn I am sorry that is happening. Hopefully someone is on here that can shed some light on this. I never had that problem when I had the ecu. Please let me know if I can do anything.

Mine is spiking high as well, to like 21 then tapers off to 18. I have APR, and it should be 19 taper to 17. The reason my boost is going so high is because my N75 is dead (figured that out today). Yours is probably on its way out as well.
