I have the stock tune in my 08 automatic HHR SS. Im looking to do a 3bar map upgrade. GM calls this the STAGE 1 upgrade.The stage 1 tune instalation is showing abut 15 different tunes for the different cars just wanna do some comparing. Even my 08 hhr auto could have 3 different Stage 1 tunes depending on the VIN. Can you guys post your stage 1 (or comparable) tunes so i can take a look to compare?Also if you coul list you mods for your tune that would help as well thanks
