Speed Limiter Issue?

[BOOSTED347]

It’s a 95 F150 with the lightning drivetrain. Using AHAC2 to tune it. Is there other things I can try to fix this issue or is it really because of the Inj dc maxing out?

No if its hitting a limiter then the injector duty cycle is another issue altogether.

If that moved it then your either hitting that limiter still due to kam correction or you found another.

Currently out of town for work. Will give it a try once I get back.

any luck?

[BOOSTED347]

Was able to try it out and still doing it. I’m thinking it has to be the psom now because the needle started to bounce around. Only does it when in drive but not in manual 1st & 2nd

did you crank up the fuel pressure? Starving for fuel can seem like a limiter. Popping, missing breaking up or it just lays down. all could be from fuel. the 19# injectors are too small unless you crank up the pressure a D said.
