How is this tune going now that you have the idling under control? I am finishing up on a 2008 4.8 with NSR Truck Norris and I am thinking very seriously about installing the higher lift model in my...

I think I have done everything I can do at the moment. Idle seems to be smooth around 680rpm MAP is around 67.5 - 70 KPa. Adjusted torque management, thanks @GHuggins I found some very helpful...

Sorry I missed your last reply, I did not get a notification. It would be nice if an app was available for phones, don't get me wrong I would much rather post from a keyboard but throughout the days...

Today I did three road trials. -25* from stock injector timing, +25* from stock injector timing, and went back to the original tune or close to the original tune that was posted in the very...

Looking back through some logs tracking the 13* is coming from idle overspeed adder. I have not made any adjustments today and I did not adjust the idle after the plug change yesterday. The idle at...

Idle is 648ish. Brakes .,.,, it does not try and jump into traffic,,, much, the tune still needs therapy and to your point at low idle that is high never thought about, I guess will need a sign that...

Thanks, wish I would have read this earlier, but I must have been on the right track because this is what I tweaked on mainly today after plugs and wires were installed. Plugs and wires made a huge...

Any thoughts on this except the obvious that I may be missing? Plugs and wires have not been replaced yet but did install WB on bank 1 side then swapped to bank 2 side just to make sure the NB...

Hello, relatively new to HP tuners and the form. So far everyone that I have interacted with on the forum has been so helpful and informative of the task at hand.

I am a Controls Engineer and...

Sorry for the long delay for an update. Not much has changed or has been done. Still no plugs installed or WBO2 sensor. I did put stock back in truck and see if it would run since this was not done...

Thanks for this information and pointers along with the log. I just went back through the tune before I started tweaking on adaptive settings before the vac leak was found. I don't recall if I...

Stomping from a stop will not even try to brake traction. It will try and power brake, but I didn't want to waste the rubber when my gut tells me otherwise. No codes set after CAM gear replaced, I...

Time was checked today along with compression and back pressure "Not with my eyes, could not match schedule today". Plugs and wires did not come in time to get them installed today. It was found that...

Dual exhaust/double stream glass packs shattered. factory manifold.

I was told the cam was just a performance upgrade and replaced the lifters while swapping cam. It's possible another issue was...

Sorry I may have failed to mention no cats. Owner still has B1S2 and B2S2 installed and oddly enough it actually looks like they have closer to square wave like a downstream cat would have vs close...

Indeed I would say very very happy about life. It has been a while since I was behind the wheel on 4.8 and never did a CAM on one until now, but I know for a fact my 2010 stock crew cab work truck...

I agree, this will probably not take place until after Monday morning but I will update the progress. I discussed this morning about some potential issues that need to be approached in a systematic...

I appreciate the feedback and looking things over. I will dig into the mechanical and see if I can find something. At this point my gut tells me what I fear is going on but I am going to do some...

Interesting observation, I was going to ask this but the mechanic shop that did this is pretty good, just don't do EFI tunes. The wrong CAM gear was put on at first and this threw me off, first time...

From what I am learning and think I know that's how I feel. Don't get me wrong the engine feels good once it's over that low end. Plus, the owner loves the sound and the overall improvements. I...

Added files to original post. This was the last trial I tried today. Thanks.

Working on tune for 4.8l that has Truck Norris NSR CAM installed. This truck does not have a traction control button and seems like the transmission is limited in first gear. I have adjusted the...
