Yeah I made a thread not to long ago about tuning I've contacted a tuner with HP tuners he's just a very busy person hopefully it gets done soon. I never thought about it but I might just swap back my 3.5 how much more power will I be seeing with a 3.5 kr free then a 3.4 with 5kr at WOT. What does WOT mean anyway? I see people using it for full throttle. Yeah I'm on speed daddy headers.
