I think I will have to wait till after the baby comes before I get the programmer and other quick mods. If you can get 350FWHP out of it it will be sold on me.

So you're looking to see 50hp out of pipes (based on 300hp with the tune)? Fat chance. If you see ANY overall horsepower increase, I'd be surprised. The main value in replacing the plastic pipes with hard pipes is the reduction of lag induced by flexing plastic pipes. When you put 22# of boost on the plastic pipe, it must first expand from the incoming pressurized air volume before passing that compressed volume on to the motor. The metal pipes don't have to expand first... they just pass on the compressed air volume. The motor will still only process a specific amount of air at a time, and that doesn't change with metal pipes... hence no peak horsepower gain.
Oh, and a larger capacity intercooler is going to put that lag back in (Note: I'm all for efficient intercoolers, and will almost certainly buy one when Bill makes them available, but they're not a panacea.) They, like ALL OTHER THINGS in this world, are a trade-off between x and y.

I think doing thing to it that don't void my warranty will be the best thing. I also don't trust these trannys yet knowing what I've seen on here so far. I've had bad luck with transmissions. LOL If GM offers a Stage 2 kit that makes 50 more hp that might be the way to go to keep warranty. Ugh so much to think about :))

I agree, I am just trying the pipe upgrade first, then the intercooler. Just so I can see the effect incrementally.
