Those are very good results for that combo and it will make more power once its dialed in

 

What do u guys think my afr should be at wot? And regular driving? What numbers should I be hoping for? I just put stock coilpacks and it went up to 517whp I lost 5trq though. Any guesses on power after my efilive tune next weekend?

 

Those are pretty good numbers. I had mine dynoed at 470 on an MD with the 10 bolt. Almost same setup without the fast. dont think I would really pick up 37 horse with a FAST.

 

Nice. the great thing is you know you have more there if you want to get it.
