I'm not familiar with SuperChips. If that is the price and then new price is $350 then that sounds like a good deal.

Superchips is a nice tuner... and as long as his truck was returned to stock, then it sounds like a good deal, otherwise, it's just a paper weight.

If he said he never took it out of the box, he most likely didn't use it. Sounds like a good deal for that price, they are not cheap. I would find out for sure if he ever used it before I bought it and found out it was not usable.

Double check the unit to make sure it will operate for your vehicle. The kid may not realize that if it's still locked to his vehicle it's worthless to you. Or it could be perfectly new as he states.

he never even used it..not even opened. some it 16 year old who just got his licsence and his dad wont let him put it on his RCLB 1500 5.3..

 

 

so its a good tuner? will it make a noticeable increase in power? what i really want is crisper shift.. my shifts feel kinda sloppy and im hoping to clean it up. dont care about fuel econ.

It will be a nice improvement for your 4 speed. You can adjust line pressure and shift points. There will not be a huge difference in power. But it will be pretty noticable change in how your drivetrain delivers the power.

 

I have a Cortex for sale in the for sale section. But $120 is a great price. Almost too good to be true.

 

Be sure to post up what you think of it.

ok now one more question, should i tune it for 93 or 87.... is it really gonna be that big of a diffrence if i run 93? will it be worth it? and if i initially set it up for 93 can i tune it back to 87?

Yes, tune for 93... and you can change it at any time. You'll see the biggest performance difference at the 93 tune. You can also get away running 89 octane while the 93 tune is installed. But you won't get as much power out of it.

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.

      Like others have said, they will all leak. Mainly at the corners.   I have owned several and the best has been my current one. Revolver x4

      LCA bolts

      By calgator73 · Posted

      About 8 months after an alignment job by the dealer I started experiencing a pretty significant clunk in the front end on hard left hand turns usually parking lot speeds almost at lock.  Occasionally get the same on hard rights too.   Discovered that the lower control arm attachment bolts are TTY and only to be used for a single use. And then I found some evidence of a TSB that indicates you can over torque those fasteners to about 130 foot pounds.   Asked a local shop to investigate and they found 3 out of four bolts loose and retorqued.   I've ordered the MOOG    K100421 lower control arm bolt kit that is completely reusable and not TTY.    Is the 80 ft pounds a realistic number?  Anyone have experience with those bolts?

      Brake Bleeding Procedure on 2026 Silverado 2500

      By davester · Posted

      subscribe to alldata.com, that will have gm's brake bleeding procedure.  and what you have to do likely varies, as if you just replaced a caliper and the MC didn't go dry, you most likely can just do a normal bleed on that corner, but if you disconnected lines at the MC or the abs unit, or let the MC run dry while doing work, you'll have to do a more extensive/complicated bleeding procedure.
