question of the day, ..... im setting up a hmt setup with a 14b and gonna run 8 psi ...

now i know i will be running a hack, and with the 440's u have to pull a hell of alot of fuel ... -40 i hear .....

no correct me if im wrong but after pulling more that -20 doesnt it stop reading of the ecu's fuel maps? is this kinda bad

would it be better to hold out and try and find a set of 390's?

do you guys think it would make a diffrence

sorry, im not to much of a tunning/fuel buff

SpankedYA!

I have never heard that. If you chip your ECU you won't have that problem!

I have 390cc injectors running 8psi boost and works fine.

But you never reach -20% not even with 390cc unless your rev limit is 11000

what do you have your vafc set to?

did u dyno

lordie

No VAFC, SMC500 idle at -31%, 1000rpm -33%, 8500rpm -23%, running very rich.

No, i didn't dyno as there is no plcae to do that in nmy country

whats smc anyone else have any other opinions am i safe to say that 390's would be a better size to run that 440's?

why do people still use this method when you can chip your ecu for nothing then you can run pretty much whatever injectors you want

i was thinking about trying out uberdata, but unfortunatly i dont know much about tuning and making all my own maps, and i need to learn the program and ---- ....

anyone know where i can find some good info about how to use the program

then all i need to do is to mod my ecu for the eeproms and get a eeprom burner right
