Thread: Ton of kr

i dont see your downpipe in there? got a 3" downpipe? that is the MOST restrictive part of the exhaust.

if you hear "pop corn popping", that is your car knocking.

a) your running way too low on your A/F ratio. that needs to be in the mid 11s when youre WOT.

b) you need more mod work to be running that 3.5 on the high compression. im surprised youre only knocking that much. you see how youre making 14 pounds of boost on a 3.5? i make barely 9 pounds of boost on a 3.4 pulley. MORE FLOW MODS.

just go ahead and take your blower belt off until you can afford some more parts.

Your inj. pw hit 27.

Inj. max out at 20~22pw.

Your pcm is commanding the A/F to go rich probably because they are maxing out.

Your fuel trims are also locking in at -4 which means its giving the car more fuel before you even go into PE, you want them to lock in at 0.

Your looking at a fueling issue, you should not be maxing out inj. on a 3.5" pulley at all. It is wierd because they go from 2-5 then jump to static(20+)

just for your information and anyone else that reads this, the injector pulse width on the 04+ cars are skewed. they arent maxing out at 21.xx like ours do.

here, read this link:

Fuel

you MIGHT be running static, but thats because something else is wrong. you should be well off with a 3.5 and stock injectors. once you lean it out you should be able to see your IPW come way down.

i still think your biggest problem right now is that you dont have any exhaust work. that downpipe is super important on our cars.

How do I get the AF ratio where it needs to be? this has happened with the 3.5,3.6, and 3.8 pulley also. I have a 3" DP i have to weld up and put in too. Also it is not topswapped it is the entire L32 engine I put in
