What price range? a friend of mine with a dodge was asking me about tuning options. I wasn't aware that there were any.

All of them

Simultaneously

What happened to kids armed with .22's, 410's, and 20 gauges?

Yeah I'm either going to get EFI or have it tuned by someone who does. I use the headbolt heater when I can but I don't always have access to them and I don't bother with it a lot because it doesn't...

Excellent, that's just what I needed to know.

My idea would work like this

1) engine starts and revs to about 2500 rpm when below -30 via [B4340] Startup friction airflow decay.

2) [B4603] P/N idle speed raised to a 1100 rpm idle below...

Some other amusing anecdotes

My friend Karlin had to be on base by morning, nothing could persuade his frozen truck to start not even pulling it in my truck (it was a 5-speed), so we took a tin...

Actually not bad synthetic 0w30 looks about like room temperature 10w or 15w. But my old roommates jeep had a 4.0 i6 that both leaked and burned badly so he had to use the heavy stuff.

When we...

Fairbanks Alaska. Interesting weather, we can see high 80's low 90's in the summer, and -60's in the winter. Not often but it usually sinks below -40's and doesn't come up above that again for...

Still working out everything I want in my custom tune. Wondering if anyone else ever put any thought to this.

What would be some good ideas for making a 2001 truck with a 6.0L LQ4 better...

And it will give lockup a quick firm feel?

So the 4L80e and the 4L60e since about 95 have had this PWM valve that lets the TCC be partially locked.


I don't really like it. I don't like the way slipping clutch feels, I think most of you...

I was just thinking about something, and I'm wondering if anyone has any insight.

Is the adaptive shift a limit that the PCM tries to reach, or a maximum shift time before which the PCM will begin...

Yeah I know not to have the pressures modified, the higher pressure boost valve causes the pressures to be magnified and whatnot.

I'm just worried it will shift too slowly. It feels about stock...

What did you drill the sep plate for firm or HD?

My current idea is to zero out the tables in regular mode, then have them set to .2XX-.300 in the performance (TH) mode.

I can't see HP in the...

My truck has a 4l80e, and a few months ago I got bored with it and installed a Transgo HD2.


I bored the sep plate for .086 which is HD shifts.

I like the shifts, they're better than stock,...

Yes precisely, a speed higher than I could ever hope to reach.


I believe the NBS trucks, at least the ones from 01-02 use the 0411.

So when I have my truck custom tuned I will have these...

This is all hypothetical so I am not at all sure what the kickdown values are. All I presently have to work with the the demo version, the truck is a 2001 2500HD Sierra, with the 6.0L and 4L80e.

Hypothetical question:
