I will assure you, there is nothing about our tuners that will lead to a warranty issue on a GM vehicle. We are the only tuner you can buy that will NOT show up on a CVN check at the dealership, and the gains are huge compared to a CAI
If anything, I think the CAI is the best/easiest early mod you can do: completely reversable, very cheap, very easy and most people conservatively report around 20 RWHP gains (plus the cool S/C whine).
Exhaust is questionable on gains without a matching tune, as it more significantly affects the air/fuel and cylinder scavenging. That, and it's much, much more expensive.
hey Mike, I live in a fairly remote part of Canada and a trustable tuner is about 8 hours away. I have a airaid and a 2.5" straight pipe muffler delete and im running a bit rich atm. I was wondering IF i bought a diablosport tuner, could I plug it in and tune for my existing mods to help out with a bit of power.
