Anyone know much about these as far as tuning? Need to know what base fuel pressure should be.
Anyone know much about these as far as tuning? Need to know what base fuel pressure should be.
Base pressure is 55-60 psi , and tunning is mostly done by Splitsec or AEM.
The base fuel pressure depends on a lot of things, a stock Viper truck is about 55 psi as mentioned above. What is on the truck to tune it, ie piggy-back, extra injectors, VEC2/3, split-sec,etc. What size fuel injectors, how much boost, etc.
If you wind up tring to tune this with some sort of piggy-back, reprogramming the stock controller to eliminate the enrichment delays will save you a lot of hair pulling and possibly your, or the customers motor.

Thanks for all the updates in this thread - it may be a few months old now, but it's been interesting to flick through none the less.
