    Best 6.0L tuner/tuning

    I 2nd avoiding blackbear. I flashed a truck for somebody using blackbear's tunes. It was a pretty healthy built lq4 with a procharger. He had it running afr's of 16:1 during warmup, horrible stumbles, wouldn't shift out of 2nd at wot, and SLAMMED into lockup(I offered to data log it, but he said...

    Allison 5sp: Grey TCM plug

    Feel like an idiot. I went through my connectors and found a 32 pin clear plug from my 99 pcm swap. Sure enough, it plugs right into the tcm's grey plug, so now I just have to add it onto my bench harness.

    Best Duramax engine model for performance?

    There is zero difference when swapping them. If it worries you, an 02 OS flashes into an 03-04 with zero trouble. For the truck side, 01-02 was the old architecture and 03-04 was the new wiring architecture, but when swappi g it makes no difference. As far as I know, the engines are virtually...

    99 FL60 mutt/conversion/repower project build

    I don't care what kind of valve job was done, or by who, I still take every head apart, and hand lap the valves before I put one together.

    Allison 5sp: Grey TCM plug

    That's alot cheaper than allison. Allison lists it for $47.35. I've got lots of pins as they're the same as the ones for the ecm, I even have a red plug from my 99 pcm swap, but no grey. Just need a plug to add onto my bench harness. I've got 3 TCM's here that can all become "01's".

    Best Duramax engine model for performance?

    LBZ would be the #1 imho, but of the 2, I like my LB7. Plain, simple, does what you tell it to with programming, and sac injectors seem to have helped with there achilles heel.

    Allison 5sp: Grey TCM plug

    I should feel bad, just picked up a 5 speed tcm for $35. Went in to get 3 0411 and a 1565 pcm's for $35 a piece, ended up 1 of the 0411's were missing and another was mismarked. It ended up being an 01 tcm out of an 8.1l, but they went ahead and sold me the 3 for $35 a piece.

    Allison 5sp: Grey TCM plug

    Does anybody out there have, or know where to get just the grey tcm plug for the 01-05 allison TCM? I'm looking to make a bench harness to flash my spare TCM's, and all the yards by me want $35 for just the 1 plug. Getting to the TCM plugs in my BURB is a PITA with how I had to bury it in my...

    Allison 5sp: 2007 LLY prime issues

    Do you have a way to check fuel pressure/vacuum to the cp3? This sounds more like fuel restriction than failed cp3 to me. Or can you hook a hose up to the prime pump and feed it from a separate fuel supply to eliminate restriction. When my cp3 went, it didn't have problems until you ramped...

    Allison 5sp: 2007 LLY prime issues

    The van does not use a lift pump, it is a prime pump from what I have gathered. It only runs before cranking to purge the air out for filter changes. It does not run when the engine is running. Check it for air leaks. My bet is your sucking air. The purge pump pushes the air out, it starts, then...

    Factory tune

    If you're close to central Florida I can flash it for you to bone stock with my Tech2. If I had a spare ECM I could flash it, then read it out with my V2, but I know not to put the Tech2 to my 01 ECM that's been flashed to an 02 as this will brick my ECM(01 ECM's are fickle pains), and all the...

    Factory tune

    That's the only one there is for 03/04, the problem is how many different segments there are for them, and they must be correct for 03-05 if you want everything to work.

    You're not alone, that's the one they're trying to get a class action lawsuit against for poor shift quality.

    Baby DMAX cancelled?

    Everything I read said it's delayed, so GM is cancelling the 2019 orders as they're going to bring it to market as a 2020 by the time the EPA finally approves it. The COLORADO/CANYON went through the same thing with the 2.8l right after dieselgate broke from VW. So I figure Fiat's recent...

    Tuner??

    And don't expect much for mpg gains on an LB7. There just isn't much you can do to help one. The best improvement I got was about 2mpg over stock, but I credit trans tuning and my lower stall converter for that more than anything else.

    ABS module problem??

    There's a known issue where rust builds up between the hub and wheel speed sensors, and it opens the gap on them causing erratic speed readings at slow/parking lot speeds. Pull the sensor out, take a grinder with a roloc cleaning disc, clean the mounting surface of the hub back to shiny metal...

    Check online for mail in rebates on mobil 1 from RK. I got $8 back on each gallon I bought last year iirc.

    L5P L5P Tuning

    I couldn't watch the whole thing. I made it to them laying out a roadmap of how to bust ppei, and turned it off. The EPA isn't playing games anymore, so why poke them with a stick posting a video laying it all out how you got around upper level security, and which companies did it.

    Looks like good advertisement and a list of who the EPA will be talking to next. A nice video documenting it all for them with the owner of the truck spelling out how he did it.
