Im interested in going EWG. Is it necessary to upgrade injectors for this mod? I did not see anything about it in this thread.

nope, currently running stock injectors, only 3 mods on my car and I put down 324whp 340 torque. TBE, spt intake, uppipe/ewg, amazing set up IMO, car runs amazing.

uppipe (be sure the ewg clears your downpipe when mounted- some have clearance issues), gaskets for uppipe, iwg bracket (or weld it shut), vacuum line, 3 port boost solenoid and tune recommended.

I am running DW 740's... If you search the members journals there have been reports of bigger injectors yielding more power with a retune.

Sorry if I missed it in previous post, but I am planning on running external wastegate and had a few questions.
1. Will I pass smog in cali with the wastegate, and if not how hard is it to swap out?
2. I have a cobb turboback exhaust and am aware of the taper to 2.5 id, should I sell my cobb and buy a full 3 inch exhaust before running the wastegate?

Answers would be awsome asap, if I missed some info in this thread that answers my questions just let me know and ill take a look. Links are great too lol
