I feel like I'm throwing a wrench into the rail by saying this but I'm currently having Don at Lasota Racing tune mine. He's been around for 12+ years tuning 2v, 3v, and 4v 4.6 setups and V6 setups, boosted and NA. He also does Coyotes. I'm surprised he is not mentioned more often. Wonder if people had bad experiences with him, but everywhere I look all I see is positive reviews.
I bought my SCT Pro Racer software from Don and paid for his base tune to use to start my tune.
Don is great with customer service and will answer any question that you have. His tune was good as well. I would have no issue recommending him to someone looking to get a tune.
