I am impressed with the result, and MORE impressed after trying the Map #2 which is more aggressive. Ideally, I want no torque dip at all. But the tune already shortened the dip from 1800rpm range (3,200 to 4,500rpm) to about 500rpm between 3200 to 3800rpm.

I have tried many different setup...
1) K&N panel + magnaflow catback ... too loud, only high rpm gains.
2) Injen intake + catless front pipe + stock catback... sounds good, noticeable gains.
3) Injen intake + Borla UEL + HFC + stock catback.... felt the same as above.
4) stock intake with AVO panel, Borla UEL + HFC + stock catback
5) above + Drift Office tune... minimized torque dip and maximized benefits from other mods.

If I would do it over again... I would jump right into Borla UEL + Drift Office tune.

Bob, if you are reading this, if you find a way to increase even more low-mid range torque, even at sacrifices of high rpm power... I will be first to visit you again. :bow:

what is a J2 HFC? is that an exhaust piece? thx
