WHo has 300whp and what do you have

Once your working with Full Exhaust HFC or headers, you will require a tune. Saw guys with full bolt on making less power then me on the Dyno.

The only thing that really "requires" a tune is headers. With intake/hfc/cbe you'll make good power. You can likely get another 10 whp out of it with a tune though. The issue I think is the cost of the UpRev tunes. My feeling is people are reluctant to drop the money on it for the power you get. I'll def be getting a tune once I add my M370.

BLM what kinda power did you make

Haven't dynoed yet. I'll be doing the M370 and uprev tune soon. I didn't want to waste the $$ on the dyno without getting a tune out of it. Right now I just have K&N's, GTM test pipe, and ARK GRIP CBE. It makes a very noticeable difference over stock I can tell you that much. It really depends on the dyno but most with the same combo of mods have picked up roughly 25 whp.
