Just wondering if anybody out there has any information about what exactly they do? There website doesn't explain really what they do to the computer to enhance the performance. From doing research everybody seems to be extremely happy with their mods afterwards. From what I understand, you have to pull your computer and wiring harness and send them in to him, am I on the right track here??

I have one with his "mileage tune" and I am extremely happy. I pull a 20' enclosed trailer and a 5th wheel RV with my truck, and the difference is night and day. More power and better mileage, what more can you ask for?

 

You can do it one of a few ways:

 

- You can pull your PCM and send it to Jesse, he will program it and send it back to you. This runs around $75.

 

- You can buy a core from him, he will program it and send it to you. You keep our original OEM PCM. This is what I did, my truck was not down except for the few minutes it took to swap them out. This is $159, and I still have the stock one.

 

- I think you can also get one buy paying for a core, having him send the newly programmed PCM, then you send your original one back to him and get your core charge refunded. Not 100% sure on this one, but I have heard this.

Glock,

 

Where is the PCM located, and what does it take to get it out??

 

Its right behind the battery (kinda in between that and the fuse box). All it takes is a socket or a wrench (not sure of the size). Its got a plastic cover on it, but the actual PCM is a metal box about the size of a book with a wire plug bolted onto it. You'll know it when you see it.

Hmmm, well mines not behind the battery, it sits below it and to the inside, between the battery and the middle of the engine compartment. Remove the plastic cover, and remove the two connectors. There is a bolt in the center of each one, use a 7mm socket to remove them. Then there is a plastic tab and a spring metal clip that need to be popped of, and it'll fall into your hands. Takes about a minute or two to do.

Jesse tuned my '04 Tahoe and what a difference it made. No more wallowing on launch, higher shift points, quicker downshifts, better economy, an on and on and on. Jesse is located about 1.5 hours south of me in Indiana and I had him do the fine tuning right in the truck with his laptop.

 

I had him tune both my factory PCM and a spare one just in case the dealership flashed my original with a newer program. I did take it to a dealership for some warranty work and asked them specifically not to flash it. The technician said "you got one of the good running ones." They couldn't tell it had been modified.

 

I just bought an '07 Crew Cab Classic with a DMax and will be taking it to Jesse to work his magic on. He just did one for a friend of mine and what a blast it is to drive. He didn't increase the horsepower so much as he changed shift points and other things that make the truck feel very lively. Vern's truck is now running about 20 mpg at highway speed.

 

I hope this helps.

I didn't wait-4-anyone and bought a Diablo Preadator handheld. I am very pleased with it, I can change my program as many times as I want without sending my pcm to anyone. It also scans and clears trouble codes.

Wait4me also offers an SCT handheld programmer (see sig). Exact same tune you get with a PCM swap, but on a hand held unit - and it can store up to 3 custom tunes. Makes is very easy to go back to stock for dealer visits.

About how much was it, and can it correct for different tire sizes? Those are two of my biggest concerns since I am also considering going with a bigger tire.

Yep, since it has a custom tune on the hand held, it'll do whatever you would have done with a PCM swap (or whatever you ask Jesse to do to your tune). But because it is a custom tune, there are no options on the hand held itself to make changes to tire size, shift points, etc. You just pick 1 of 3 tunes, and away it goes.

 

It was $369 shipped. Free updates for the life of the vehicle (less shipping charges).

just got mine about a week ago and it was a breeze to put in. I got more of a towing tune and a balls to the wall tune when you hit the hot button(tow/haul). It runs great and I can deffinately tell the diference in gas mileage and the giddy up too. was well worth the $159. I had a hypertec in before i had this and this is way better than the hypertech handheld.

 

what kind of scan tool will do the crank relearn?? anybody know?

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      By glenn27 · Posted

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
