If you have an auto, with a stock TC, the 305 hits right where you stall at. other than that and the 4deg seperation in duration they are exactly the same :crying: ---

They are alot cheaper. you think the pcmforless tune is good enough to stay with, or do you think you can get more power out of a dyno tune? I used a laptop to upload the tune after it was emailed to me. I’m sure you can get more out of a dyno tune, but for a mail order it was pretty good. ---
