LT1 guys, need some help.

@Spyderking69

maybe in a manual car, but not in a stock auto LT1. the 503’s powerband doesnt kickin until 1800rpm, where as the 305 hits at 1500. 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:

i went 13.4 with just a cc305 and boltons that was running 9.0 afr also with a tune that would have been a 12 second car. but now with the ls1 and a cam im shootin for 11’s instead of 12’s

yeah madz28.com thats it, thanks Jeff… theres also another one that if you have a laptop and the wire then send you the file and you can upload it yourself. 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.
