Grim, I have a MPT perf race 91 tune. I haven't data logged it yet but the couple times I drove it I got dtc codes. Plus, my wife hated the tip in on it.
My let has lots of power but has perfect tip in, wife can't tell the difference. It also gets great MPGs. The cherry on top is Erick has excellent cs and gets tunes and revisions out quickly.
It's the Thuggish Ruggish Bone
