Thread: Which would be better?

I currently have a 3.4 pulley now. I've had to drop my timing way back to get to 0* KR. Would i be better off going back to my 3.8 pulley and adding timing?Also, I'm having to run a little rich to help with the KR.

bigger pulley and more timing would make the car faster. i dont know why you cant run that 3.4 with downpipe, plog, a wideband, and a tune USING the wideband.

I'm not sure either. I'm heading out to PRJ on tues to see what he can do for me with a tune. I'm getting a lot of KR without pulling my timing a lot. I'm sure there is just something I'm missing and I hope he can help me out. If not I'm gonna swap back to the 3.8

Sure it isn't false?

110 octane kills all kr.

Yeah but if you can afford to always have 110 octane gas in your DD that you don't need to be driving a grand prix

I can't afford it! I put in a few gallons when empty to verify that it wasn't false KR.

i bet your fueling and timing tables are off.
