80lb injector tuning

[farmtruc]

Just got done tuning JJ's yellow STS truck after a few upgrades. With a fuel cell, good lines, Aero Pump, and 78-80lb injectors, this thing kick ass!!!
The injector flow rate is now at 52% and fuel pressure stays at a strong 58psi.

The stock 6L is pushing 14lbs of boost in third, so hopefully we'll see some 11's from it.

This truck definitely hauls ass.

I tuned this truck in speed density mode and it works very well. Nice start ups, great drivability and holds a solid 11.2 a/f ratio through all gears.
Once a truck gets this far, there's no other option.

Not sure what this post is about, lol, just figured some of the info would helps someone.

Yeah Allen I was wondering if you actually did much SD tuning. Do you use the 1bar OS? I see guys all the time over on the Hptuners forum running SD, but I was unsure how often you used it. Is farmtruc going to use an SD tune?

Ya, the truck will be SD tuned, especially at 18psi, hehehe.

Well, JJ&#39;s truck didn&#39;t run so good. We came to the conclusion the stall converter is just too damn loose and doesn&#39;t load up the converter.
He has a 3200 stall in it, and at the light, I can easily get 5KRPMS&#33;&#33;&#33;&#33; from the converter. It just stays at the high rpm level and doesn&#39;t pull very strong. This is through 1st and 2nd.
Once this bad boy hits 3rd gear, the converter locks, 14psi comes in and it&#39;s gone&#33;&#33;&#33; When the converter is refreshed, all gears should do this and low 11&#39;s are in reach.
We&#39;ll get it, definitely next time.

see ya,
allen

i read somewhere else that another guy was having trouble with a 3200 flashing upwards to 5000 rpm&#39;s....that way loose right there....
