My real concern is the noise the motor is making under cold start up, Im starting to wonder if I have a pinched oil pick o-ring? It is really bad at start up and then its just flat out noisy during the rest of the time. I really wish someone with more knowledge then myself could listen to it. Put it this way I don't feel good starting it!

 

Being a little lean at cruising speeds isnt' going to hurt anything. IN act, in other countries, GM programs that very feature into them.

I've always been a BIG advocate of DIY tuning, and the only way you're going to feel comfortable doing it is to do it. It's a little scary at first, but before long, it will come like second nature.
