I have the Livernois tuner and could not be happier with the service from this company. They use the MyCalibr8tor tuner by AIW instead of the SCT tuners. I have been very pleased with the two tunes that I have used so far on the Raptor and I can get new tunes when needed at no charge as long as I own the tuner. This is actually the second F150 that I have used this tuner on, the first being an ecoBoost. When I purchased the Raptor Livernois converted the tuner via downloads of firmware and tunes at no cost. When I added the modified Airaid CAI they came thru again with a new tune at no cost. Thank you Livernois for supporting the product you sell and most of all the customer(me).
