dfi or fast
dfi or fast hard to beleave but i ended up purchasing both systems, we are installing a 408 motor from forced fed with fast 90/90 set up and zex dir port nitrous. Motor is being installed in a 2600 pound sand rail with 25 inches of wheel travel front and rear. both systems are set up for wide band, i have alot less money in the fast system but would like to know what everybody thinks would be the better way to go. one concern is the ability of the ecm to take a beating off road, getting these cars 20 feet in the air is not all that hard.
Dfi Or Fast was not sure about the ability of the big stuff 3 to hold up in the conditions we drive these things in. i have seen sand rails with fast and dfi with no problems. also i purchased it both systems used.
