so do you guys think i would get the most performance and driveablilty with the 15's and my 366 or step up to a 371? or what other turbo options do you guys recommend?
What should fuel rail pressure be at on H&S hd300 tune? Or any tune what's a bad number to be at or below? Sorry for mini thread jack
I plan on it Greg, still deciding on where to go for custom tunes. I was just asking to see if my HPFP is still ok. Didn't know it was in the tuning sorry. Still new to custom tunes
Sorry for the misunderstanding I am NOT interested in upgrading any part of my fuel system til the truck is closer to paid off lol. I'm just trying to get the best mileage possible and reliability. I just wanna turn the tune down if I can't keep rail pressure up due to a weak or failing pump. So I was curious so I can check next time! Thanks
yea im just trying to make high 6's or 7...i mean if i could do that on a 371 and maintain rail pressure that would be what im looking for, I just didnt know if i could do that on stock injectors. currently i have 94k on the truck and prob 50k on the injection pump and around 1k on the airdog.
Yea im.running matt at gear heads tunes. ...so do you think I could run a 30% and tune down or you think a 15 is better?
So matt won't have a problem.tuning 30 ' s on a stock hpfp?
Do you ever think that when they installed the 30% nozzles and they had gains down low it was because they had the extra fuel, and we're maintaining the desired pulse width down low, then up top lost some power because they weren't maintaining the higher pulse width and the higher rpm/injection per minute rate.. I don't doubt that there may be gains down low, but it's not that there aren't gains up top, it's that the truck isn't running right (by not maintaining rail pressure)so it isn't making the power it could be for the amount of fuel the tips are capable of. But it's been proven over and over that these pumps barely maintain a race tune on stock injector tips. I just think putting any nozzle on with a single stock pump will promote premature failure of the pump. Might as well get the right pump set up, put bigger nozzles on, and dial it down. I'm totally for that. I have a street truck and 100% nozzles. I absolutely will never use the fuel 100% nozzles will supply so my tunes are backed down, and are still being backed down to where I'll be satisfied with pretty clean power. But I have lower pulse widths with better atomization because the fuel is probably staying in the bowl, and I maintain rail pressure.
