ok i have a 2012 gt/cs manual 6 with roush tvs with 85mm pulley and Jlt cold air , bbk long tubes ,off road x-pipe and fordracing catback and 3.73 gears.:shrug:
I will say Alex is close on his estimate. What I find interesting is...early this month, a guy posted w/ similar mods as Alex and I but out down ~650+ iirc with a Lund remote tune. Not starting a tuner debate, but it seems that tvs dyno results vary a lot on here. Dyno is a tuning tool. I'm taking mine to the track early April...good luck!
