1999 F-150, 4.6 2v

[Seakot]

I'm new to the forum and you know I have some questions. The 2 wheel drive truck is basically stock. But it dose have a few mini mods. 4.10 Gears, larger air intake, Magnaflow and a E- fan. The hand held Predator has helped me get the truck running a bit more responsive. I am just using the Diablo tune with small changes to parameters.
Can you recommend a performance tune for 89 octane? Or maybe just a good 87 octane setup. I'm looking for performance not fuel economy. Also it shifts hard into second gear. I made some adjustments for that with no help.
Anyway, you guys ROCK. I'm just trying to wake up that 4.6L....

I have a U7153.

you can simply pull a few* of global spark for use with 89 or 87.

Thanks for the info... Can you help me to better understand how Global Spark adder works. So it just gives a stronger spark??? Also what about making a small advance on the timing?

it adds timing globally, not something to mess with unless you have a good reason and no exactly what you are doing, and why
