Just today I went to East Coast customs at Northgate, and they dyno tuned my 2009 VE Alloytech (so not the same set up as you). What I can say is though, for $995 they got an extra 22kw (which is great), but the massive difference is in the drivability. Idles a little lower, a much more refined sound from the exhaust, crisp take-offs and generally just a lot smoother. I had a couple of interior rattles in certain rev ranges before the tune, but they are all gone now. All of this points to them being pretty
So very happy and would definitely recommend them.
My set-up is: growler CAI, extractors, high-flow cats, and X-force through to the back.
