I see how it is- we get it down to the very wire and then we start gettin the crap!
Really though, should know pricing tomorrow (the machine shop gave us pricing on all but two items we sent him).
The ArcII on stock turbos is actually likely to show a gain, however it is the larger injectors that do it- because of the massive amounts of timing thrown on because of how the ARCII works. This timing can be good, but you have to factor for it.
This is why sooo many people blow their motor's at 16psi- they get a fuel controller and don't factor that they add the timing. The timing kills.
I recommend an ARCII for 550 injectors. Anything larger, and I'll recommend the EMS- too many people have too big of a problem with 720's and the timing it adds. Heck Trevor lost a motor on 550's because of the timing.
Just becareful- there is way more going on than most people realize.
And stock turbos are getting ready to be pushed as far as they can go- jayson's car is finally getting to the strip.
