Hey everyone, I'm now using a Jet Stage Two chip in my 305tbi. I originally had the timing set to 6 degrees advanced, Im just wondering if this chip bumped it up even more and if so, should I knock the timing back down a notch or two? My mods are, bored 30 over, 9:5:1 compression, Jet Chip, LT1 cam, 3inch magnaflow exhaust, dual snorkel and 3.73 gears

 

Most performance chips will bump your timing. I believe this is why most of the chips require a higher octane fuel.

 

have the jet stage 2 dont really notice a difference

 

with the LT1 cam you are prolly gonna end up advancing the base timing even more anyway. i doubt the chip changed teh timing much, prolly only a few degrees across the map.

later
