frankss If its more of a white smoke that would be an over fueling issue.... maybe a bad injector. You have a IR Thermometer?

Timmyh No, I meant the 3500 rpm bit. Foot to the floor, 5th gear at 2200 the boost gauge finally starts coming off 0. Around 3500 it hit 12. I let off shortly after.

As far as the clutch slipping and de-rating, I never noticed it before swapping turbos. Just let off as soon as it started to slip. I have not changed the tune yet and I just got done running a short data log. I have a south bend sitting on the shelf waiting to go in. Just trying to figure out why it will hardly idle and smoke like crazy first

Yes, leak test has been done. Not seeing any

the man in black Was "12 pounds of boost at 3500rpm" a mis type or did you mean to write 3500 rpm.

N of 60 Engine will derate with a slipping clutch. New turbo and connections have obviously been leak tested? It does not sound like you changed your tuning since you changed your charger? You have data logged these events to show your tuner?

Timmyh Clutch is sitting in the garage, ready to go in. Trying to figure out why the truck barely runs before I spend time with that

N of 60 Factory clutch and performance tuning? Start with matching those two and go from there.

Timmyh Truck is right at 100,000 miles. Only mods are the deletes with ez lynk for tuning (korey Willis tunes) and now this S363 from High Tech turbo

Timmyh Hey all, I'm at my witts end with my 4th gen. Problems started around a month ago. First, I would consume a tank of def in 200 miles. Dealer wanted 2200 dollars just to look at it. Decided to solve that problem and a few others permanently instead with ez lynk. Truck ran great on a 700 mile trip, towing a trailer across the Rockies. Only thing wrong was my exhaust brake was acting up and not working much. Next morning it was hard to start but ran fine otherwise. My wife took the truck to town that night and I noticed a blueish smoke coming from the exhaust when she got home. I noticed later that both my oil and coolant levels were dropping. These led me to believe the turbo was failing. Jump forward to last night, I get the s363 drop in from HTT. After install, I fired it up and the smoke from the exhaust is worse, truck idles HORRIBLE and I can only make 12 pounds of boost at around 3500 rpm. With the ez lynk and stock turbo, the clutch would slip on stage 2 and above. Last night, I cranked it to stage 5 and floored it and the clutch held. Truck has absolutely no power.

Any help at all would be great. Or if someone wants a 2015 6 speed manual 3500, come get it
