ok heres what goin on my tuner call me and says my map sensor maxed out. i'm not surprised so i up graded. he calls me today and tells me my car is leaning out at 6500 rpms (rev up motor) he asks me if i modifide the fuel pump and i told him yes he said he not sure why its runnin lean but hes has to dig into it more. he also said that he had to gap my plugs. Now heres where im puzzled i'm running vortech tuner kit, 440cc rc injectors, walboro 255 fuel pump (w it modifide) i've benn on this site learning alot and a kid i met has been helpin me too. correct me if i'm wrong but what i'm running should b more then enough to give me the issue of running out of fuel.... also he never put a fuel psi. gauge on it befor he called me i dont know would you put a fuel psi gauge on it soon as this startedb to see where its at. i dont know im starting to get the feeling hes tryin to get CASH out of me.. could this really be happening i mean the fuel issue with what i have.. If anyone knowsw about this stuff please let me know what you think........ Thanks

 

Somebody help a local guy out!! Good luck!!

 

what pulley are you running? what engine management (utec, osirus)?

 

im useing osirus and as far as the pulley the one that comes with the turner kit i think its the 8 pounds at least that what i was told from the door.but he told me i was makin 10 pound at 6400 rpms this make me wounder tho

 

did you buy your kit new or used? new kits come with the 3.33 pulley on the bracket which usually only yields 7-8 psi of boost. hitting 10 pounds at 6400 would imply you have the 3.12 or possibly the 2.87 pulley.

as for the fuel issue, you should be OK with the walbro assuming it was modified correctly. did your tuner indicate whether you're maxing out your injectors / near 100% duty cycle?

 

he has the rev up motor, which comes with the 3.12 pulley. depending on what pulley system you have, you might have your tuner check the injectors duty cycle like Bigc said. if its the 3.12 pulley with that setup you shouldn't have any problems with running out of fuel.

 

thanks and thats where im at with it. it's just not makin sense i have the 3.12 pulley and i should b good... just tired of the bull**** with people not givin me a straight answer. i to the point wher e i'm like stop f**kin beatin aroubd the bush and lets figure it out........ thanks guys any body else has anything let me know...
