Injector/ fuel delivery requirements (request assistance) Well, i'm in the homestretch of my LT-1 heads/ cam exhaust/ clutch upgrade and am now turning my attention toward upgrading the fuel sysyem. The motor is a stock bottom end with the following mods:
Ported intake and heads with 2.00/ 1.57 Manley valves
Comp cams custom grind 224/236 Dur. 502/ 520 lift (1.5 ratio) 115+3 LSA
Jet-hot long tubes
Y-pipe with twin random tech cats
Vortech SQ trim (6 lbs)
Fuel system (current set-up)
stock injectors with FMU
Vortech T-Rex inline pump
I am seriously considering ditching my FMU and upgrading the injectors and fuel pump. What is the consensus on selecting the right components vs. horsepower?
I also want to perform my own tuning, which program has the best track record for the OBDII system? Which is the most user friendly? I would also entertain a mail order tune as a baseline and use tuning software for all upgrades.
I have performed exhaustive research and there are just too many options out there to make this decision without first asking the question.
Cheers!
