I installed the spool in the spare 9" housing. The truck currently has 4.33's, a bit steep for highway speeds with a 3 speed automatic. This case has 2.75's which may be a little far the other way, but my hope is that it will perform sorta like a power glide with an overdrive. I don't think torque is going to be a problem so I figure it will be fine.

Diff is swapped, driveshaft is in, just have a list of about 5 little things I need to do before I set it on the ground and take it for a test drive in the parking lot.



Oh and Rocky Mountain Race Week was a blast. Car ran great for the most part, trans (T5) lost 3rd at the track in Pueblo so we were forced to drive it 1,2,4,5 for the next couple of days. It sounded awful, but didn't completely fail. Haha.

Hey looky, it works. I drove around the lot for a few laps datalogging then decided to do a little burnout. It was almost out of fuel so didn't drive it a long time but I did get some good data. Converter *might* be ok, it is a little loose but not obnoxiously so.

I finally got insurance on this thing so I can start driving it and tuning it. I had been dragging my feet because we were focused on the 83GT and then doing an engine build and swap for my sons's 1998 Durango. It turned out real nice. Hughes intake, KB pistons, Eagle rods, Comp XR268HR, Magnum RT heads with 2.02 valves. He did all the work and is pretty darn proud of it.

Finally got other projects taken care of so I can start tuning on it more. It had a big stumble when the throttle was yanked open. I think I have it tuned out now.
I tried using Autotune in TunerStudio yesterday but the truck was almost out of fuel so I think that was screwing it up.

To this day Ive never had good luck with the Tunerstudio autotune. On my Procharged Mustang the autotune always wanted to lean out the fuel mixture, its completely possible that I didnt have the configuration setup exactly right but logging and altering the tune seemed to work better. The autotune really screwed me up when I tried to use it for cold start tuning.

It definitely wants to pull out too much fuel, which I can crutch by altering the target AFR table, but I probably won't mess with it any more. I'd rather do it myself and learn what the truck wants.
I really prefer to use MSDriod to tune and log. It runs on my phone so it is much more convenient to use and logs GPS speed and location.

The MSDroid look like a nice setup, thanks for the info.

Converter swap.
I originally put the PG Raceshop PGX-D (3800-4100 stall) that was in the Mustang in the truck. I feared it would be too loose and I was correct. It flashes up to 3500 just mildly accelerating and shoots to 4700 if you hammer the throttle. No good. I picked up a Hays 97-2G24F converter, 2400-2800 stall, with anti-balloon plates to replace it. This should tighten it up where it is not just slipping all the time and making heat.

I have been chasing a lean problem under boost. Nothing I did with the tune would correct it. I couldn't determine if it was a setting I had wrong or a mechanical problem with the fuel system.
I routed the fuel pressure gauge up to the windshield wiper so I could watch fuel pressure. Sure enough, it was dropping like a rock under boost. I had just filled up the fuel cell, so it was not low on fuel. I decided to check the fuel filter and there is where I found the problem. The filter was completely clogged with fuel cell foam fuzz. I pulled the foam out of this cell right after I go it and this must have been the residual fuzz. Anyway, that fixed the problem. I uploaded an older tune and took it for a drive an it works exactly as expected now. Whoo hoo! Wastegate is set to at 5 psi right now and it is a blast.

Do you have a wideband gauge installed?

Absolutely. It is on the steering column and AFR is also displayed on the MSDroid app.
