]Hey guys, well I just installed a 2.7" pulley and some 60 lb. injectors on my 06 cobalt ss. Spent a couple hours this morning trying to get it set up right. Still needs alot of work on the fuel (however due to my wideband harness falling and sitting on my header, I have to buy a new sensor)....and I'm sorta lost on tuning the MAF right now....and I'm seeing a little knock in the upper RPM as you can see on a couple of the pulls in this scan.....any suggestions that can be made would be appreciated...Here's a link to my thread on HPT forums with a tune and a scan...thanks

I haven't looked at you log, just your tune. Try the multiplier method on the first set up injectors thread for your IRFs and modifier. Also, your offsets are a tad high.

 

cool, I'll give that a shot....thanks

 

anyone else have anything to add?
