Hi guys. I guess this is more of a tuning type question than single turbo specific, so bear with me. I recently installed my XS T04E kit w/a PFC running the Forum's single turbo map. Well, when the car is accelerating at WOT if feels ok, pulls good to 4k rpm then the boost really kicks in nicely. However, from there on up, though it's pulling ok, the engine sounds like it's labouring a bit to climb the revs, the power and acceleration just feels a bit flattish. But if you just ease off the gas pedal slightly out of WOT, you feel the car start pulling a hell of a lot better & the engine sounds a lot smoother. The plugs are brand new. Any ideas? Too lean? Too rich? Ignition? There's no misfire. Mods are 1300 secs., SX FPR, RP fuel pump, FMIC. TIA.

That single turbo map on the forum sucks. I used it for 2 days and then sent my PFC to XS. I suggest yo0u dont use it.

 

Just curious, what problems did you have w/ it?
