If you're doing the gears yourself take your time and be careful. If you don't set the gears up correctly there will be increased wear on them. I had the housing that holds the mechanical locker...

I have thought about that but the injectors I have were only $50 haha.

I looked around for pricing from some online places and prices varied heavily as well as the service provided. I found ones...

Reviving thread for one last question... (TLDR: Injectors are Chevy 8.1l injectors from a work van with who knows how many miles on them.)

So, after a month I finally did a thing. I rigged up some...

I'm not really sure how to answer this question so I'm going to just throw some shit out and hope it helps. It would be nice to know what you're working on or working with for an idea of where to...

If you're in P/N I'd still look at the base running airflow and see if maybe it's too high. My truck had a defaults of 17@-4, 15.20@32, 10@104, 6@176 (Grams p/sec), mine are now 23.50@-4, 22.82@32,...

Idle hang can be cured different ways that I've seen. Is it idle hang at well, idle? Or is it coasting and it's in a cruise like mode? If it's at idle you need to remove base running airflow or,...

Hahaha, Sorry. I should've started with that. That'll help a lot as it opens all of the tables. Like I said earlier though, the injector timing you'll probably want to go back to stock. Change all of...

The injection timing normal and makeup may need to be changed back to stock values(0.05 ref periods less). Messing with that changes when the injector fires, and I don't know enough about when it...

So, I changed out the injectors this morning and put my factory ones back in. With one prime cycle it was enough to turn over even though it died instantly. It primes again if it doesn't run and it...

Have you used the data from the injector control section? I know for me when I updated the tune from my 1999 that had the 19 lb/hr injectors to the current 25.2 lb/hr data it worked wonders. Truck...

Makes sense. I think. :)

Alright, so I replaced the O-Rings top and bottom on the 8.1l injectors. I then removed my factory injectors. Put the 8.1ls in, reconnected the harness and bolted...

Hey guys, hopefully I've got a quick and easy question(s) if someone knows. I replaced the engine in my truck with a 2002 Silverado 5.3l engine and slapped a mild cam in. At WOT I have 90-105%...

Thank you. I'd like to invest into a wide band sensor but it's not in the budget currently. Plus I gotta do some research first to figure out how to get it to be recorded in a standard MPVI unit....

Apologize for my absence. Jimmy, that is a lot of information that seems to make sense but I don't understand it but that's OK! Thank you though. Haha.

Back to the false knock and fuel issue. The...

I get that without a wide band o2 sensor that I won't get the whole picture but the narrow band o2 sensors should give me a pretty close picture when dealing with normal driving. So I did a fair bit...

My truck is a 1999 GMC Sierra 1500 with a 5.3l engine from an 02 Silverado. It also has a BTR Stage 2 Truck cam (212/218, .553, 113+2). Now I have been tuning the truck myself, with basic knowledge...

For that catalytic converter question, when mine clogged up it was sending all the unburnt fuel down the pipe and I believe exploding inside the cat. So what I did to test whether or not it was my...

Yes, the OS' are interchangeable on the 99-02 PCMs. I'm still attempting to figure a good way of doing that myself. I did write an 02 file to my truck but it wouldn't start as I think the VATS system...

Hey Sefhinny, I don't know if this even pertains to you or not as I unfortunately didn't look at the tune file. However, I've been messing with deceleration fuel cutoff on my truck and if you pass...

Hey Maroon, I'm still a newbie tuner but from what I see in the tune and from the log is you still have CAT Over temp Protection still enabled. It's in [Engine->Fuel->COT, Lean Cruise] tab. Basically...

Hey Josh, I'm still a newbie myself but sort of figured out some stuff and I'll try to relay that information to ya. My knowledge is fairly limited and all derived from my 1999 GMC Sierra 1500 with a...

Thank you both for the help. I left my tune the same and just plugged in the sensor and it started reading correct intake temps. I got far better results than the absolute garbage I had previously....

I didn't think about the fuel issue being that -38 temp. I was only thinking about the spark. I'll have to run another test tomorrow. So all I need to do is leave the MAF plugged in, but keep it...

Edit: Truck is a 1999 GMC Sierra with a 2002 Silverado 5.3l engine with a BTR Stage 2 Cam (212/218, .553, 113+2).

Hey folks, I first started trying to get a 0411 PCM tune for my truck but I...

I don't exactly want to turn off my anti theft as I don't want my truck stolen, ha. I can do the relearn that's not hard but what I'm curious about is how emissions would like my computer having a...
