Kevin thank you so much for taking the time to write this. I was wondering if you could share what, if any, prior mods your car has? I'm strongly considering hellion's TT kit for my GT, the plan being to forgo any of the standard standard I/H/E/Tune based mods until after the kit is installed and based on your pictures, it looks like you might be starting with the TT kit as well.
Thanks a ton,
-Mike

OK. Got everything buttoned up.
Soldered and heat shrink the connection for the fuel pump trigger.
Then I wired up the Hobbs Switch from the 2nd pump.
Here you can see, the Hobbs Switch triggers the 2nd pump.
I was also able to mount my new catch can set up. I had to use spacers to set it away from the firewall so it would be easier to access and give room for the fuel pump wiring fuse.
Here she is now all finished up!

Close, I-35 in MEXICO!
Had someone offer me money for them when I was installing the turbo kit so I sold them. Figured I would try something with a different color to match the C/S stripes a little better and Steve @ True Forged had a set of SS. So I figured I would give them a shot. I think they go well with the theme of the car.

Since I do all my own tuning and tune on the street, I haven't had a chance to get the car on the dyno until the other day.
I wanted to make sure I wasn't going to break anything and I didn't want to go over 650 RWHP with the stock motor so I pulled a few degrees of timing out and made 2 quick pulls just to see where I was at. I kept the revs down the first pull and stopped at 6500 just to check. Then made a pull to almost 7000.
This is on the wastegate spring pressure that is only supposed to be 5 psi. The boost was around 6 psi and went around 7 psi up top.
Anyway, I did everything myself in my garage on jack stands and tuned it on the street.
Info on the set up. Stock Motor, Stock 6R80 Auto, Stock Converter, Stock Gears. 3" O/R X and 3" Magnaflow Competition Cat-Back. ID1000's, Full Fore Fuel System, E85.
Here's a few pictures and videos.

ok this just made me rethink my WHOLE plan on going with a tvs blower or the kenne bell 2.8lc blower. Those turbos sound awesome. Does it come with a BOV or did you get one? I love the way the spooling sounds and when you let off.

The bov is for when the turbos go into a vacuum (no throttle) it's releases the pressure in the turbo. Some bov's recirculate the pressure to help build boost when throttle is opened again thus lessening lag. Some just let it go into the air. For a bov think an air compressor. When you're done you can pull the valve that empties it.

Forgot to mention how bad *** that set up is. Great write up as well. Thanks for the time you put in not only on the build but to help us too.
Friend of mine just did a custom set up. Fabbed it all up from scratch. TT is def the way to go with the 5 oh.

Thanks. The new 5.0's are great platforms for boost. It's amazing what little boost it takes to make great power with these cars!
