What mods have you done to your LT1?

I originally had a hotcam/no emissions/MAF tune. I then changed to a speed density tune (same mods) and it was great. I had the first tune done in 02 and this latest version in 06. Both times the engine started and ran great.
The price is better than most and customer service is great.

Dumb question: Why change to speed/density setup? I thought the MAF setup worked better.

I was trying to "clean" the front of the motor up (I had the standard F body 90 elbow with a filter). That was then, if I had it to do over I wouldn't. Not that SD is bad, but taking Hot air (IAT 150) directly into the intake will hurt performance. That is why.

Not a whole ton. Cam is the stock cam (I know, I know...). I have a bunch of bolt-ons. Cold air, headers, throttle body coolant bypass, smog delete, 3.42 gears, etc.

Big thing with PCMforless is that they have done a million different LT1 combinations, and more than likely have already done a combination close to yours.
