All I can say is do it, My gas mileage is a bit worse but I drive kinda hard, and with the throttle hijack the throttle is supper touchy. My shifts are VERY firm( 7 spd auto) they will actually whip you in the seat
and if I hit it right shift into second will chirp!
Overall performance wise I am fully bolted and the car is very quick/fast.
I know we don't share race stories but the short of it a few new V8's(Camaro, mustangs) have had their eyes opened, and this Sunday I had a SLOW walk past a Supercharge GS350, even wife was :O!
He will completely change your car, Seb really knows his stuff, I still haven't messed with the TQ management tho.
