    Q's for the guys who have GBs DVD

    Im assuming most of you had pretty good tunes with raped VE and PE tables before getting the dvd. Now with the proper injector setting are your cars running any better then before? If so in what way?

    Ive read all the stuff on the forum about how crucial having the right injector info is for idle, PT, WOT etc and im not disagreeing with that, im just looking for real life experiences between a good raped tune and a good proper tune

    I can honestly state that it is an obvious improvement in drivability and fueling control.

    Look at the big picture. The MAF is a very very very important input sensor. In theory the PCM could tell you the RPM based off the MAF. Yes and other sensors, but based off the MAF or volume of air. The MAF xfer must be done first

    MAF vs TPS vs Load or Map and a bunch of constants

    Yes the DVD expense was worth it to make injectors behave as they were designed for our application. Especially the larger style injectors!
