Full Throttle 4" MAS pipe problems

[forcefed3.8's]

I just installed the 4" pipe on my car, and it won't idle. It fires up for a second, then dies. I have a Gen 2, set it to 4" Mega MAf or whatever it says. I put my 3.5" LS1 back on, and it runs great. What needs to be done? TIA

We had a "few" problems also...........We are "still" working on the problem when we have time. Some cars runs GREAT with the 4in and other ( like ours' ) NOT-so good.

Make sure the MAF harness is plugged in correctly (match the wire colors).

Also see what version firmware is in the GENII. You should have 1.07 if using the 4" MAF. It should display the version on power up.

Thanks guys. My Gen 2 is a ver 1.03, I saw on the fullthrottletech site that ver 1.07 can be downloaded. How do I install it into the Gen 2?
