Need HELP!!

CCasidy2016 · Feb 29, 2016

Ok, this is my first post on the forum but have been lurking for a while. I have learned a lot of great things. I recently picked up my first powerstroke. A 2012 6.7 XLT with 120, xxx miles. I got with Mike at NoLimit and purchased a ****** kit with the SCT X4 programmer. So after receiving my stuff last week I finally got the chance to get everything installed. When I finished up it was late so I was only able to start the truck in the garage and make sure there were no leaks and what not. Well I felt the truck was really laggy so the following day I contacted NoLimit and they sent me some new tunes to try. I got home from work and loaded the updated tunes. I let the truck get up to temperature and took the truck for a drive. The truck will not build any boost and has no power at all. It's so bad that with the pedal to the floor the truck will barely break 30mph. I have been in contact with Mike trying to get this sorted out with no success. Also when revving up the engine it has a huge hesitation and takes for ever to get to 3k rpm's. Have any of you ever experienced this? I have checked to make sure everything is tight with no leaks! I tried updating the programmer and reloading the tunes. The truck is not throwing any codes at all. Truck ran great before. Please help! I am at my wits end and really don't want to return this thing to stock.

I have contacted Mike. He is working with Gear Head to try and figure out what is going on. I just thought I would throw it out there to see if anybody else has came across this.

Have you updated the tuner itself lately? I had the EXACT same problem and the tuner was not updated. Truck made absolutely no power, than didn't move at all. Would step on pedal, it wouldn't move than all of a sudden the power was there. Try putting the truck back to stock, updating the tuner, than reload it. I have an SCT as well.

EDIT: Never mind just read the last sentence of your post and you did update the tuner. Maybe try a different tune in the truck?

CCasidy2016 · Feb 29, 2016

Yes, I have updated the tuner but with no help to my issues. I have tried all the tunes I have with all the same result.

Sorry to hear you are having issues with your new tuner! Are all the sensors plugged in (map, temp sensor after intercooler etc.)? Have you tried disconnecting both batteries (more at least 5 minutes) to do a reset?

CCasidy2016 · Feb 29, 2016

All sensors are plugged in as far as I know. I am away from the truck right now but will double check them asap. Haven't tried disconnecting the batteries but I will.

Txfiremn · Feb 29, 2016

How did you update the tuner? It needs to be plugged into the computer and not downloaded over WiFi. That was my problem with my SCT.

CCasidy2016 · Feb 29, 2016

I plugged it in to the computer to update it.

if you're refering to a KAM reset it's a little more involved than just unplugging the batteries lol . anyway, we will get this fixed. about to send you an email cody .

CCasidy2016 · Feb 29, 2016

If someone would like to explain the KAM reset I will give it a shot.

CCasidy2016 · Mar 1, 2016

Mike, haven't received an email yet.

Sportchassis06 · Mar 1, 2016

Call him

Nope. I wish! Called Mike today and was told Luke was working on the issue and that he would call me. Still waiting on a call! Tried disconnecting the batteries for a while and ******** the device updater and reinstalling. Still the same issue.

CCasidy2016 · Mar 1, 2016

Yea, I'm going to have to do something soon because I can't keep my truck sitting much longer.

WHY NOT · Mar 1, 2016

Tune the truck back to stock, just on the tune and try starting it. See if it revs up normal and stuff then. I wouldn't drive it around or even run it long with everything off of it like that though. Just to see if taking that tune off solves the problem. Seems like something didn't cross over right. Its not smoking a ton out the tail pipe or anything is it?

CCasidy2016 · Mar 1, 2016

Nope no smoke. I will give it a try tomorrow and see how it acts. As soon as I tune it back to stock I get a reduced power message. Will this affect the way the truck revs?

Notneb · Mar 1, 2016

Rsduced power message will come on until all the d3leted items are out back on. Computer will keep it like that until all connectors are back on. Even then I disconnect my batts to reset everything. I do this every damn year thanks to stupid emissions laws... Hope you find out the prob soon!

Yeah it may, I'm no guru with this by any means just a though that I had that popped into my head. I would almost put money on its something stupid like a sensor somewhere though.
