Got a slight hesitation when boosting ATM... No loss of pleasure so thinking injector/not enough fuel problem... Got 440cc injectors, any recommendations on upgrades on them/fuel pump?

Cheers

So many possible causes. If you put make and model and year down. Then follow it with what mods you have and then add when you last replaced plugs, leads, air filter etc i'm sure you'll get some possible and more than likely causes to your hesitation issues.

Sorry good shout!

It's a 1995 WRX

It's got 440cc injectors, tdo5H turbo, FMIC (all checked no leaks) recently gone all oils (gearbox, diff, engine) cambelt and water pump inc all pulleys, and all plugs etc!

Only reason I thought fuel, was because its only when trying to boot it!?!?

Presume you have had a map to suit the FMIC ect?

Elliott Watt
