Trouble with Hypertech

My otherwise stock 6.0L (2001 2500 HD) has been fitted with a K&N FIPK. This past spring I installed larger tires on an aftermarket wheel. I decided to get a Hypertech programmer for the new tire size and pick up some performance along the way.

When programmed at the 87 octane setting, I get severe pinging when I get aggressive with the throttle. With 89 octane, minor pinging with the programmer set at 87. I have not tried the 93 octane program/ gas. I called Hypertech on this. Their excuse was that I am flowing to much air with the FIPK, and that I should remove it and just use a K&N filter with the stock air box.

This sounds like a poor excuse to me, and I'd rather not dump my FIPK and then turn around and buy a new element.

I may also try to return the hypertech and try to find something better.

Right now I have returned the truck to stock tuning and all is well.

I need some help here! Thanks.

Try cleaning the mafs. Those with K&N's have had problems with the filter oil getting on the sensor wires in the mafs and causing pinging.

If you really want to make an improvement get a Wester's and sell that Hypertech!

I've never had any pinging troubles but I just have the K&N drop in not the K&N FIPK. I never run less that 93 in my truck either.Maybe go to the higher octane fuel settings and see what happens.

I have had the K&N FIPK and HPP3 on my 2000 5.3l for over 50K miles now.

I run 87 octane with the HPP3 set at 87 and not pinging...

 

I have read many posts where people do experience pinging but set the HPP3 higher and it goes away...

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
