Wondering what kind of performance/mpg gain I can expect for my 5.3L CC? Don't really plan on doing any other mods to it, but would like to get rid of the torque management and gain a little power and mileage. Want to keep using regular unleaded as well. Anybody got any real world results.

I don't know of any actual dyno #s, but the giuys I've talked to have been very happy w/ theirs. I'd advise against having all of the TM removed if you're not going to upgrade anything else. The tranny won't hold very long. I'd do 80% removed and put a cooler, billet servo, and shift kit on the trans. These 4L60Es are pretty weak, those mods will help it live having more power going through it.

I have an 01 Tahoe 5.3 and I am very happy with Brian's tune. I have the 93 octane tune, got rid of the slop in shifting, and locked out overdrive until 50mph. I gained 3 mpg city and highway. This has been a HUGE performance gain! Just tell Brian exactly what you want and I am sure you will be satisfied.

What is the cost/time involved in installing the cooler, billet servo, and shift kit on the trans. Im thinking about doing a 5.3 tune as well on my '03 but am in the same boat, dont want to do alot of other mods, but dont want to mess anything up either.

Bryan can do whatever you want!

I had the PCM forless tune for about 100miles on my 04 1500cc before I sent it back to get reprogramed (something with an error code issue).

I liked it while I had it and it hadnt even broken in yet.

I say it is a worthy investment.

I absolutely love my PCMforLess tune! I've never been one for calculating fuel economy, so unfortunately I don't have any solid numbers for you there. I can tell you this though, my truck really moves now, night and day from what it was. Bryan is an awesome guy too, great to deal with and he really knows his stuff.

      Transmission Woes :-(

      By No1UKnow · Posted

      Hello All!   My 2019 Colorado 3.6 LT, 4WD Crew Cab has approximately 77,500 miles and I recently began experiencing the well-known transmission shudder between about 30 and 65 mph. The problem had worsened to the point that I could no longer attribute it to road conditions - and I had decided to bring the truck to the dealer - when recently, I experienced a sudden loss of power while driving at maybe 40 MPH. Several warning lights flashed, the “Check Stabilitrack” message appeared, and the Check Engine, Stabilitrack, and Traction Control icons remained illuminated. The truck regained driving power, but it stayed in a low gear with unusually high RPMs for the speed. (limp mode?) Because I was only about two miles from home, driving slowly, I was able to make it back and run an OBD-II scan, which showed fault codes U0101, P0700, and U0100. My next trip in the truck was to drive it to the dealer the following day. That trip began normally, but after about a mile I experienced another loss of power, along with the same warning lights and the same “Check Stabilitrack” message. As before the truck remained driveable, but again operated at an abnormally high RPM-to-speed ratio and seemed stuck in a single gear. About a mile later, the dashboard lit up once more, this time displaying “Check 4WD.” Soon after that, I arrived at the dealer. I have verified that the truck still has its original factory transmission fluid, which means it has never received the corrective fluid exchange outlined in GM Technical Service Bulletin #18-NA-355.  That was Thursday of last week and I've heard nothing yet from the dealer.    According to Technical Service Bulletin #18-NA-355 and the build date of my truck, my truck should have the newer LV fluid. I've done a little research and read something about a problem with the wiring harness as well.   Anyone have an insights into this situation?  Thank you!!

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.
