HPOP affect mpg?

I swapped out out my stock 15* for a modded 17* from joey. this 17* throws more ses lights than the last hpop. and was getting 15ish. now its 14 best.


is this true or not?

Nooo, hpop should increase mileage. More volume and steadier pressure, everything should work more efficient. Now is this before or after the chip?

Well, do you have access to AE, or another way to record ICP??

Hey Jarrod, I'm falling a bit behind on my emails again, sorry for the delay.

#8 makes me a little curious, but it could be because it's the long lead injector(kind of normal).

PW, about right.

470-488, a little low, but anything that close in psi(by only 20psi or less) is pretty solid.

Oil temps are excellent!

Duty Cycle is also a bit low, but that's a good thing, because it tells me that the pump is very efficient.

Have you got a chip yet?

Thanks,
Joey@TE

Well, you certainly shouldnt be tripping 1211 with stock tuning and no chip. Hook AE back up, set it up to scan ICP, duty cycle, oil temp, and pulse width. Hit record at the top left, and drive!
