Hptuners ftw. Anywho put ure hptuners back on... Or datalog look at fuel trims. This will tell you if you have a boost leak or if ure just far off.

 

How many car lengths should I be putting on a stock cobalt ss tc? Just for future reference. Lol

 

more like 4 bus leghts...u should be putting down 100whp over a stock cobalt. while hes in one gear u should have already gone through two gears.

 

Get it dynod, or go to the drag strip.. until then. Assume driver error or tune error..

All 4 things I mentioned come back to you doing some work that doesn't involve the forums lol

 

I would check your compression just for piece of mind, you could have a valve hanging up from carbon build up. It happens with DI.

 

Trifecta norm dont worry.... Hahah jk

 

12 is crazy rich. On a decent tune you should be running close to 13afr/.88lambda. I bet Vince didn't lean your tune for the added fuel from the meth and it's slowing you down. I wouldn't be surprised if you had some kr going on too.

 

not

 

drive my 98 cavalier then go drive your car right after. you car will feel like a jet. but im going to go with the tune.

 

kr? im not sure i know what that is.

 

Knock retard. Lnfs seem to like detecting knock and pulling timing when they run too rich.
