Next step would be returning the Evo and getting a custom programmer to account for any modifications you might make.

 

Both!

 

Zex is next

 

I agree that high flow cats are a waste! I got long tube headers no cats, true duel, no x-pipe, to 10 series flowmasters dumped before the rear axel, It's the best set up.

 

Why would he return his Edge Evo? It would only cost him $25 to upgrade it to a Gryphon plus $30 per custom tune why waste time returning his, waiting to get his money back & then buy the Gryphon from PHP and have to wait for that when all he has to do is send his to PHP & get it done.

 

Jesus Christ dude, did you set out on a quest to have the loudest piece of **** in town with absolutely NO torque? You do realize the engine needs a TINY bit of back pressure for torque, you know that thing that make the truck leap outta the hole and tow the hell out of something? 30 series flows is pushing it and unless you have a stroked and forced inducted motor under the hood, I highly doubt you have the power to back up that grunt the truck makes.

 

I kinda think he meant to say retune.

Check out the set up

 

As long as the system is sized right and tuned for the changes it is fine. The engine does NOT need backpressure. Please read:

He can either upgrade the evo or return it to get a CS or CTS. I guess I just like the latest and best device which is why I said return

 

This.
