    Cant seem to control/alter pilot injection (LB7)

    What I found was the dsp tables didn't respond to changes, it used the main table in all positions. But yes, I have also had problems with pilot tables tuning lb7's. I brought it up on the efilive forum a few years ago.

    Trans Service Advice

    I have one I did that will not hurt a stock trans. I didn't add much to the bottom end, just set it up to bring the power in quicker, optimize timing down low, and set it to hold the torque out longer in the power band. Torque is what slips them, so I didn't increase peak torque, just made it...

    Duramax Tahoe. Tuning the allison 5 speed

    Before you go doing ANYTHING! Check what operating system is currently in your ECM. It is common practice to put an 02 OS in an 01 because the 01 OS is not mapped out the best, and is known to have many "ghost issues" when tuning. If your 01 was flashed to an 02, best case scenario flashing it...

    VGT turbo controller for lb7??

    Seems they offer both. When I looked they only show a picture of a mechanical wastegate version, but in the lower description they say they offer both.

    What threads are the cooler fittings?

    Yes, it's a -10 with an o-ring where the fitting goes into the case iirc. Just make sure and use a hose that can handle the heat. I used some 275 degree rated hose on mine and they kept leaking from the heat breaking the hose down everytime I towed something. Ended up going with some 325 degree...

    VGT turbo controller for lb7??

    That uses a mechanical wastegate controller on a vgt turbo. It works, but would defeat the purpose of having an on demand turbo brake, and have you running sky high boost killing your mpg's at cruise I would think.

    What threads are the cooler fittings?

    For which trans. I know the cooler ports in the bellhousing are a -8 AN for the 01-early 03 trucks, and -10 an for 03+. Cooler fittings at the radiator and aux cooler varied.

    Factory Tune

    I wouldn't, not with the history of corrupted lb7 ecm's with tis flashes. I would have it flashed with EFILIVE & a V2. Efilive uses there own flashing sequence.

    Twins with Twins, Anyone?

    I forgot about them, they were the ones that built the aluminum shaft for my Suburban. They specialize in carbon fiber and drag racing shafts.

    Twins with Twins, Anyone?

    There's Florida Powertrain on 60 in Tampa that builds shafts as well as Spicer, and other driveline stuff. It's probably worth a call to Mastry Marine in St Pete, they specialize in Yanmar diesel repowers, and have done just about anything you can imagine including building jackshafts for high...

    VGT turbo controller for lb7??

    Fleece sold a controller years back, but I don't think they sold many. You might be able to find a used one.

    GMC Cyclone

    Because in 1991 they made 280hp and 350 tq which was more than the vette had(excluding the zr-1). Just found another one with 78k miles listed on fascistbook for $17.5.

    GMC Cyclone

    There's one for sale near me, but he wants $29.5k for it. It's been for sale for 2 years, so I don't think he's very motivated. Source: https://youtu.be/2DyWdmLEI-A

    I spent about 6 hours running 225-230 on my lb7 when my fan clutch quit on me. The stock t-stats don't even go full open until 230 as per GM.

    How's everyone doing with this virus crap?

    How about New York, New Jersey, Michigan, and a few others that PURPOSEFULLY sent infected patients to nursing homes, essentially signing death warrants for those at the highest risk of infection, and doing this while the government supplied hospitals & such that they DEMANDED sat EMPTY! How...

    Lb7 injector rebuild? I need help Please!

    Unless you have a Bosch certified shop, you cannot buy anything except some seals, crush washers, & nozzles. This is why you cannot rebuild your injectors yourself, you cannot buy the parts to do it. Bosch does this because it take 10's of thousands of dollars worth of equipment to do any sort...

    Super Duty Duramax

    Was swapped to an lb7 iirc, but yes, it was a 6.4, then a 12 valve, and finally a duramax.

    Super Duty Duramax

    There's one over at CompD, it was posted here about 5 or 6 years ago.

    Twins with Twins, Anyone?

    I believe there was problems with the magnet half blocking the holes. If you're not running the magnet you should be fine.

    Lacking Power 2001 LB7

    Mine with a 6006 02 OS would not code even when rail was dropping down to 90 mpa, and sometimes lower. I was smoking like crazy but could tell it was down on power, data logged it, and seen rail pressure was only holding about 12,600 psi on my daily tune. Pissed me off because I found it the 1...
