Dearest Evo friends, I have a 2011 lightly modded GSR that desperately needs a new tune. (modifications listed below) Can you please recommend anyone other than AMS and Strictly Modified? What are your thoughts on Boostin Performance? I live in the Chicagoland area, and I would be open to a road tune or dyno tune. Any help is greatly appreciated.

ETS Intake, Cobb XLE BPV, Grimmspeed 3port, MAP UICP, Walbro 255lph pump, MAP o2 eliminator downpipe, MAP testpipe, Buschur crossflow exhaust

Thank you!

Devon @ Boostin does an awesome job and I would definitely check them out.

APM hands down.

Definitely Boostin if I ever need a new dyno tune. Went with Kunal road tune as he tuned my car few times before I knew of Boostin.
