Had all the work done in my sig and got my car back yesterday. Runs like sh_t. Wants to stall and has little power. I don't think the shop adjusted anything but only installed the parts. I'm going back thursday to get the gears put in and they said they will be using a Predator to adjust the speedo. They said it will have more power when it's tuned with the Predator but should it run this back now?

 

needs tunning for sure.

 

needs tuning and i dont think a predator is going to help it any.

you need hptuners or ls1edit for sure to help with the VE..IAC...TIMING...IDLE SPEED...etc.

 

i agree, you definatly need a tune for that cam and intake, it throws everything off. a preditor is just a waste of your money, you need a dynotune.......
