are these programs refferring to what JWT programs for you? which fuel injectors does each program run and what other associated equipment is used with each of the different programs?:confused:

There is no such thing as a 1 bar=14.7 psi and 2 bar=29.4 psi JWT program. All cars come stock with a 3 bar=44.1 psi which is the most common JWT program. 4 bar = 58.8 psi is a program designed by JWT to get the most fuel out of a given size inj without having to go to larger size injs.

i see, thanks for clearing that up. :D

most people choose to run the 4 bar fuel program with a 250-300 whp goal w/ 370 cc injectors?

I wouldn't say "most". There are only 4 of us as far as I know, right, Dre?

I just ordered the 4bar, but it's for the 550cc inj...
