i dont have custom tune. there are not any companies that have released a GOOD tune for the 5.7. unichip is about the only one that would be worth buying, it costs $700+, and i dont think it is worth that.
and no, i have no corrected for the larger tires. stock tires are 32'', these tires are 33'', so there isnt alot of difference. and when i told the story above, i compensated for the difference. when i say i was going 65....i had the cruise set at 63.
