Lol, yeah I should have mentioned the intentions at first. It is a fun build. Prochager is in the works down the road. I've built it to accept boost.

It was actually 1,308HP on a stock bottom end 5.3l. Type in 5.3l big bang theory.

I will keep everyone posted on the project.

Thanks everyone

You don't want to buy a PCM already set up. This is considered a canned tune. HPTuners is what I use for tuning. You can get on the HPT forum, ask all the questions you want and get good answers from others. Plus the tune repository is full of tunes that you can compare to yours.

Awesome Mike! I had been looking at HP Tuners as it looks to be the most supported in the LS world.
What is your take on HP Tuners MPVI2 + VCM Suite?

It'* the same thing as my MPVI1, but the MPV12 supports WIFI I think. Mine connects via USB. Software is the same, and the pro version supports up to 5 additional external sensor monitoring.

Awesome man! Appreciate it. I just sent HP Tuners an e-mail with what I need to confirm it will all work out. Thanks again!

Yupper.
