Its just a simple question. This is the deal I put in the PFC this winter, I had a Gforce computer in before. I used to pop a NICE blue flame after every shift once i was in the second turbo. But now with the PFC and non-seq I dont even have a teeenny backfire. I did the F\C adjustment, all 3 to about 8000 and nothing what so ever. Ive got a bumped up fuel map too. I know it sounds ricer but I loved giving anyone that wanted to play a little scare. Any Ideas (And yes its a straight exhaust all the way)

 

no one?

 

Have you had the PFC mapped? on anything approaching a standard car the base map is rich enough to pop and bang on every gear change. If you are not getting this at all I'd suggest getting a wideband on the car and check if there is something amiss.

 

Ya...I put in new maps. I know its **** but I have a autometer A/F and its running really rich.

 

im actually just the opposite, i was thinking of getting a PFC to reduce the amount of backfire. will the base map eliminate my backfire?
