Default Tuning my lq4

I've been looking into tuning for my 1500hd

I know about black bear, but was curious about what my other options are.

I plan on running a 93 octane tune, and want to do an oem electric fan mod.

It has the larger air filter box, but might make a tube to run between the throttle body and air box.


I didn't know what was involved if I should be capable of doing my own, or if an efilive I'd really worth the $900 vs the hptuner, or just getting a scan/tune.

Information is all over the board, and I seem to have a hard time finding hard evidence vs brand loyalty

I just heard that Steve Morris can tune the PCM and dyno tune it. It doesn't cost a lot from what I hear. It's right by you too.

Steve can dyno tune it and get every possible hp out of it.

I have worked with LS a few times. He tuned my jeep 5.3 and several of my friends trucks also. As he says, his tunes are like mailorders, but allas, he has tuned allot of 6.0 stuff. He also may have more options since I have seen him.

I have also heard good things about pcmforless??

I dig 6.o trucks, but they sure are thirsty.

well, steve morris wanted $650/first 4 hrs, and $100 for each hour on top of that, and they would expect 5 hours for a tune.

waiting to hear back from Ryan. I should email him too, just posted on his FB wall.

Ryan's the shit! His car is badass too. I own HPtuners, that's what Ryan uses as well. Unless you want to know how to tune and want to put the couple hundred hours of work into learning, just have someone else do it. Especially if it's just intake and bumping timing type stuff.

I see the benefit for being able to scan to do my own diagnostics, and be able to calibrate for tire size if I want, but I don't think it's worth $500 more for the system.

My question is would he charge his rate each time I want something changed?

That's between you and him. I would charge you, my time isn't free nor is yours.

good point. I wouldn't expect free, but I wouldn't expect a full tuning session because I went to a different tire size or something trivial like that.

I think you'll find Ryan very down to earth. He does it because he enjoys it, not for a living.

TJ @ BEI in Nunica

He uses HPT

Since you still use MAF and don't have much exotic done it shouldn't cost anywhere near $600

He is real reasonable for re-tunes. If you bring it to him, its pretty much free...

He re-tuned my jeep, and really just cost me some gas money. He went with me and a friend to the dunes and re-tuned both of our 5.3 jeeps. Added a tranny tune to make them work better on the hills....

$600 covers scheduling a tuner to be on site if needed, open ended time on the dyno and the labor of strapping the vehicle to the dyno and setting up monitoring equipment. Smaller shops also have $100-$200 worth of licensing credits to buy and larger shops have to cover the initial cost of the unlimited license for that specific vehicle group.


On your truck with air intake and premium it's not this elaborate but on a custom setup this is what I'd do. First I'd have to get the thing to idle and run at low rpm which depending on cam and setup can be a trick in itself so I'd have to spend some time there. Then on a GM vehicle I'd fail the maf and do SD tuning first which involves hitting 0-XXXXrpm in almost every map category for each rpm interval, then do a maf only tune through the rpm range, then turning both on and putting it through a series of pulls to see how both tables are interacting under different loads and map setups. Then start WOT tuning doing a series of pulls bringing the rpm up gradually. Once the A/F is where I would like it, if I had a dyno I would now start pulling WOT at various timing intervals to find peak tq and peak hp number, then blend for wot. After this I still have to go back and look at timing tables driving around and address any high load, high timing areas for KR. Once that's all said and done I have to come back and redo my idle air config stuff for the final idle tables.............then hopefully it runs and drives like it should It took me more time and reading than I care to comment on and I still learn something new every time. A full out tune with all that done for $650 is a bargain as far as I'm concerned

I'm planning on going with Ryan. He is guessing around $300.

Gotta get a few things on first though.

Does that include dyno time?

Don't think so. I'm 99.999% sure he doesn't have a dyno. I'm more looking for economy than power, better drivability, and torque management removal. I don't need every hp squeezed out.
