I've been running Smarty Touch on level 5 for about a month and have gradually lost power to the point it just feels like stock. I then put it on level 9 and it felt like it was back to level 5 power for about 2 days now it's losing power again.

Rail pressure is about 5000-6000 at idle. Spikes at 24000 wot. When I stab it it drops to about 13000 and takes about 3 seconds to start rising. It wasn't doing this before. It was usually pretty instant.

Egt's are normal and only spike to about 1200 on hard pulls. Boost spikes at about 37 psi.

I was told there was no way my stock clutch would hold level 9 but it's doing it no problem so something's not right. It's not making the power it should.

This truck is a 2005 2500 with nv5600 stock LUK clutch, stock injectors and turbo 300,000 miles.

Any help is appreciated.

 

Seems like things have really slowed down with these diesel forums. I wonder if people are getting their information some other way now?

 

I think most of the guys are seeking info from youtube and AI chats

 

This place has definitely changed over the last few years ...... and the changes are not good.

Can't think of any reason why your truck could change the way you describe, except am wondering if you are absolutely positive that the changes that you programed into the Smarty actually took hold. Did the Smarty accept the changes?

I have the Smarty jnr on my truck.

I guess it did. I didn't get any errors or anything. I'm to the point now where I have to put the truck back to stock, then reload a tune just about every three days. It runs great after the tune is loaded and gradually loses power until it just feels like stick again.

 

If I remember correctly, it started a steep decline after the site was sold. Too bad, as it was a great site.

Merry Christmas to you,

Replying for the updates.

 

Me too.

 

No. I just reset the Smarty Touch every 3 or 4 days. Pretty annoying.

 

Yes, you are right. How is everything going now?


 

Looks like A! is awake early today. Another first time poster asking an irritating useless question.

 

Sounds like the Smarty Touch is losing fuel pressure. Check the pump, filter and pressure sensor. If those are fine, the clutch might be slipping under the extra torque.
