    Error Codes and Warning Lights After Rear Differential Rebuild

    You'll have to have a 'good' scanner to clear those codes.. Then just just drive it and see if any of them come back...

    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    That's pretty normal... Try a different oil filter brand maybe - like a wix, they have higher flow rates than most - even the acdelco's. Also, make sure you have good quality clean synthetic 5w30 20 psi is ok at hot idle... I'd be more concerned if your oil pressure was only 30 ish at 2,000...

    OBD2 information overload.. not sure if I should be worried?

    You are pretty normal there... The IAT should drop down as soon as you start moving... Mine hang around 110-120 sitting still on a 90* day... So about 20* over ambient... You might want to check how your air filter box is sealed ( or lack of) to the inner fender where it gets it cooler air from...

    Go back to the factory tune and just turn off the rear O2 sensor trouble codes... That is all you need to do

    Keeping coolant and transmission temps under control when towing in the summer heat

    I have looked into fan tuning w HPT.. On the trucks/suvs there is NO SPEED Override option The fans turn OFF at about 45ish mph... really no matter what you do.. I don't have issues with it running hot until I'm pulling my large travel trailer at about 55 mph. And that will tend to up my ECT...

    For Those with Aftermarket Camshafts

    I suck at trying to post videos and pics... The one app that I used for this website went to crap a while ago.. And my smart phone is old enough that it isn't smart anymore... Maybe one of my kids can help me !!!

    6.2l DOD Delete parts list

    I did mount the derale cooler behind the bumper with the fan .. I just use a toggle switch that I put at the center console to turn it on .. I really only need it when towing.. And since i pulled the supercharger everything runs a little cooler anyway

    I'll give gwatney a call for sure... Yeah it's very different idle so maybe it's just the tune I've been on the HPT forums and such and gotten it better than the crappy tune I paid $$ for, but not nearly where I thought it would be... Thanks for the suggestions

    For Those with Aftermarket Camshafts

    I've been jacking around with the HPT for 2-3 weeks straight, trying to smooth out my idle.. It runs pretty strong (i think).. But it's really rough/choppy under 1000 rpms. I have to bring idle up to 800 for it to really idle OK.. Remember, I took off the EForce supercharger and installed...

    According to cam card: Intake Centerline is 105.0* Exhaust Centerline 121.0* So lobe sep is 113* with 8* of intake cam advance ground into it

    That must be the difference then... figured the 113*+8 would be a pretty mild cam. I'll go find my actual cam card and find the IC* and report back

    I did a dod delete cam this spring.. Retaining VVT. The specs are in my Signature. I'm still learning and tweaking the HP Tuners to get it to behave at idle... But my question is: Did your new cam make your exhaust a lot louder ???? My Yukon now sounds like a cammed up racecar... It's very...

    Are these problems related?

    You may have a weak fuel pump.. It's a "module" assembly... So when you take it back to your shop for the fuel leak issue, I'd have them install a high quality fuel pump module assembly... This will prob kill 2 birds w 1 stone BTW: use a delphi, gm, acdelco OE quality fuel pump or you'll be...

    6.2l DOD Delete parts list

    Please report back when you get the work all done. I used the VVT truck stage 1 cam from gwatney as well... My base idle is pretty rough... i didn't really think a cam this small would "sound" lumpy at all.. Maybe I did something wrong, so I'm curious about others' experiences with it

    2014 Tahoe SSV - Cyl 6 misfires. Wires & coil swapped, still misfiring.

    I did that fix to a friends 09 gmc 5.3 L and it did work.. I just used a cheap push rod from the parts store.. You'll need a pushrod that is slightly smaller in diameter from the stock one to fit into the DOD Oil Hole.. I put antisieze on it and had to pull it out with a vice grip, but it did...

    2014 Tahoe SSV - Cyl 6 misfires. Wires & coil swapped, still misfiring.

    There have been counterfeit plugs on the market.. But if your shop got them locally then they are more than likely OK I just went thru a misfire that went from Cyl #2 to a random P0300 after a dod delete cam swap. It ended up being a bad coil pack - which is very unusual... My engine has...

    I guess 18.4 mpg is to be expected?

    I never got that good bone stock with the DOD working... Maybe 17.5- 18 at best You are doing something right !!! The 6.2 in awd 6K plus truck !! You are doing fabulous

    2014 Tahoe SSV - Cyl 6 misfires. Wires & coil swapped, still misfiring.

    How did your spark plugs look ???? If you did wires, you prob need plugs too.... If that's the cause.. It could be a DOD lifter failing (or the VLOM) as well just read you did plugs a month ago Which plugs did you use and where did you get them from (yes, it could make a big difference) ??
