Which would be better?

[2001GTP]

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.

 

[BwolfGT]

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

 

[2001GTP]

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.
