I just want some opinions on which pulley I should use a 2.85 or 2.7? I have both. I've been running the 2.7 for a while now but I've had people tell me to go back to the 2.85. Would I notice much difference in power by switching back? Also I have zzps pcm and I'm wondering if I would notice any difference switching to ottps pcm?

 

i would just keep to the 2.7 and get meth...lol

 

How much timing are you able to pull off w/ the 2.7 and @ what AFR?

 

not sure to tell you the truth. I have 2.8 and i got a basic tune on mine to just get my meth kit going...going to play around with it next month when i get my tvs. I only added 2* of timing and the a/f is around 11.5 Like i said, i didnt go in depth with the tune, just to get it running. gained 14whp from it though

 

very nice

I'm curious tho what the OP has timing and fueling wise on the 2.7

 

Keep the 2.7. Torque will be lost going up.

 

I will probably keep the 2.7. Now which pcm would be better for the 2.7 zzp or ottp?

 

If you are wrong about something, ZZP will actually try and demean your intelligence. If you want to see something, PM me.

Personally i think OTT will do a better job with working on the tune to make it right.

 

I agree...
