very little bottom-end after tune ???
#1
went and got my truck tuned to day and it has very little power below 3000rpm. it has trouble getting off the line, i was told it might have a weak fuel pump. has anyone had troubles with a weak fuel pump or had trouble with getting low-end power out of there truck? the trucks the exact same as everything in the sig.

i was thinking of trying them. just wanted to give the guy im using a chance. so no one has had issues with a ground or anything messing with only the bottom end power? i know its a long shot i just hate to think im gonna have to have it tuned again.

you have a cammed 6.0 with a 3600 stall and have problems getting off the line? that doesnt make any sense. you may need to look into a new tuner. it should blow the tires at speed under 20mph.

there could be other issues but if your tuner cant tell you whats goin on then i suggest you look elsewhere. i tuned a camaro that was a turd no matter what i did to the tune. but after looking at some data the mass air was bad. should have seen the smile on the guys face after he replaced it.



You have a tuner issue, sir.
