ok so it looks like with the IC upgrade there are significant IAT decreases but the Cobb tune shows only a small increase in actual HP output even when updating to stg 1+ or stg 2? I have my AR DP sitting in the closet but am thinking about selling it as I'm not interested in swapping it every year for inspection. thoughts? updated IC is a given at this point bit why does the tune seem so conservative? josh?
