The MAFT Pro is a piggyback which offers fuel control, timing control and boost control.

As for finding out which injectors, get the part number off of one... it's stamped in the black plastic part of the body.

Do yourself a favor and get a wideband sensor on there as soon as you can so you know you're not running lean. I'd recommend the Innovate Motorsport LC-1 as the least expensive option.... and it's a VERY good unit. (plus it'll integrate with any standalone system or the MAFT
Pro)

Wow thanks a lot you have been very helpful....I'm pricing the MAFT Pro and wideband sensor to see what I'm looking at...After I get these installed and tuned I feel a lot safer while driving my car....Will having the MAFT Pro eliminate the need for a fuel cut defender?.....I guess this is going to put a hold on me replacing my HG and head studs....I just want to get this engine reliable first and fore most.
