GMTuners / Sinister Perf. FAIL!
So Ryan got on his high horse again, this isn't the first time he's contradicted all the big names on turbo stuff, and now he won't even do, at any price, a speedometer correction on a complete reprogramming he already did for me. That's not acceptable customer support. I've been polite and civil, I didn't insult his parentage, I always add a tip for a beer or a steak dinner.
I found another tuner with very similar pricing, more reasonable than most, in fact, and does what I ask without arguing nor acting like a teen geek in his momma's basement.
