Do I have to get a tune?
I recently put a LQ4 in my Chevelle and need to know if I need a tune to safely drive it....or will I hurt the motor if I don't get it tuned. I am running a MAF, IAT, and O2 sensors so shouldn't it tune itself in some respects? I plan on tuning it in the future, but just want to drive it a little until I get the money. Here is what I have.

What PCM are you using? If you're using the one that came with the engine/ wiring harness, then it might be ok. Since you do have a cam, it would best to get a custom tune to get the idle, and part throttle in line. Make sure your fuel pressure is 58-60, the tank is vented properly, and the trans, and rear gear settings are close, it should be ok, but still...........it's best to have it done right, and it'll be trouble free. Unfortunately, a $150 tune isn't going to cut it.
