First, I just want to say that I've been thrilled with AM's customer service over the years. These guys have taken care of me a few times in ways that I consider to be above and beyond the call of duty. I have bought plenty of parts from other good vendors but AM stands out as being consistently great...I wouldn't hesitate to buy from them again. I have to say that even the men and women who answer the phones genuinely seem to care and want to help...it's a really rare experience these days. A few years back, I picked up an SCT tuner and "Tunes for life" through American Muscle...which includes the handiwork of Bama Performance, of course. So I back in the fall, I requested some new tunes (after running the stock tune for a few years after the #8 piston failures early on in the Coyote's life cycle). The Bama V2 tunes seemed to be getting positive reviews and I thought it was worth a shot. Well, I tuned the car not too long before putting it away for the winter but all I can say is that so far, the 91 street tune made a noticeable difference, at least in throttle response. So far, so good...and the car hasn't blown up yet. I know everyone has their loyalty to their tuner...but is there any worry about engine failures with the current Bama tunes? Is there any other specific reason to not run their tunes?
