A 7730 has one injector driver designed for saturated (high impedence) type injectors. This style is available to +50 lbs. I am running 30's atm on my 7749,(a 7730's fraternal twin). BW

First off, if you wanna goto 7730 you can do it now with your existing harness. You'll need
1) 7730 ecm and memcal
2) Knock sensor for 7730, or a pack of resistors
3) Map sensor, with plug (from carb car, tbi car, etc)
And like an hour and a half of uninterrupted time. The dox are in the tech section.
7730 Solved all my maf problems, and I've only got about an hour into the chip. This is just basic setup stuff, no optimized VE changes, etc. And I spent over a year with the $68 (165) setup.
