I have a friend with recently bought an 05 tahoe with a Magnacharger kit on it. The Dealer overwrote the tune and now i'll have to tune it. I had heard Magnacharger was selling these kits with EFI Live tunes they developed. Would anyone happen to have a stock file of theirs i may look at for a starting reference? I believe they use 42lb injectors with their kits.

thank you.
