Ok ill change them back till i can fit my adjustable reg and go for a retune, because the tuner said lasttime that he had to set my limiter at 5800 cos it ran out of fuel so trying to see if more fual and pressure will make a difference

Says here hes tuner told him it ran outta fuel


i doubt it.. ive seen 4.0l's pull up to 190 rwkw n/a with std injectors and no j3...

yep, id say with those mods he'd be pushing 150-160 rwkw....... if anything with the stock injectors the tuner would scale them down just so it wouldnt be running rich as is

and yeah, ive ran the same cam in made in a couple different specs, with a couple different tunes, the only prob i came across was the crow XR spings were not up to the task

so no head work or bottom end work at all, Just curious as i just rebuilt my engine about 6k ago and just had a dyno done and only managed 124.8@4400rpm, mind you i have advanced the cam quite a bit about 3 degrees, because i shaved about 30thou off the head it will retard the cam. Very surprised by the huge variation in the figures but mine isnt tuned yet have j3 ready to go just letting the motor run in a bit more. Soz to hijack just curious.

Nah i have been thinking bout getting a port and polish and maybe shave it a bit but im. already making pretty good power dont no if it would be worth it... and with the j3 it will make a big difference in your tune ggoodluck with it mate
