The 7M-GTE's KVAFM isn't very restrictive at all until you start getting into some of the significantly larger turbos. A fuel controller and better intercooler may be a better use of your money.
Anyway, I haven't heard anything about the v3 on the 7M but I really hope it's less finicky than the v2 was. A lot of people found it to be a major headache. Wiring should be very simple, probably similar to the MAFT Pro's wiring.
