Well...you get what you pay for usually...

Remember, you can have cheap, good quality or fast service...but you can only pick two.

Cant wait to see how it turns out myself...I can only imagine your anticipation.

Truck got dropped off this afternoon.

With the meth setup, and as much as I drive, decided on the 7gal reservoir that'll mount in the bed. Also decided last minute to go ahead and finish the exhaust out the back. Will be either Corsa or Magnaflow. Hopefully Corsa, but whichever of the 2 they can get in and installed before I make it back from my trip.

Shooting to pulley the blower so that the motor actually sees 11-12psi.

11 days and I should have her back. In the meantime, its aloha for me!

Update --

Ran into a couple snags, but nothing major. Should have the truck back tonight. The LT's that were originally received had the wrong flanges. That caused a couple day setback to get the right ones. Then the catted Y-Pipe sent, ended up lacking 18+ inches from meeting the factory cat back. Because I need my truck back, a spool piece was fab'd and put into place for the time being.

Corsa says they won't have a catback for the truck available until after the first of the year, so hopefully by then we'll have the proper Y-pipe and can replace the current one when doing the catback.

Did get to here the truck cranked on Friday. Here's a few pictures and a quick exhaust video for now.

Leaving shop, they're still tuning on it. Last pull I watched was 490rwhp/473rwtq. Not sure on the timing, but haven't even started the meth or increasing timing much. Motor is seeing 8.5psi.

This is still on 20" wheels and 35" Nitto Trail Grappler MT's, if it matters. I want the motor seeing 12psi, so it won't be long before a pulley change.

Awesome numbers so far. It sounds great too. This should certainly turn a few heads.

Thanks a lot. I'm liking the sound as well. Going to scream for sure once Corsa releases a catback.

Not sure how much it matters, but those numbers are 4th gear pulls.

If you check there site, its basically there Camaro packages. Reaper package and twisted package. The additions to those were converter, gauges, meth, and their breather system.

Just talked to shop. Final rwhp before adding meth was 503. Going to go ahead and get a smaller pulley ordered and on the way. Drive it like this for a month or so then turn it up a little more.

Should finally pick it up this evening.
