You won't be able to use the 3"-2.5" coupler. The compressor has a va band flange on it that most people cut off, they then use a 2.25"-2.5" silicone coupler to connect the compressor to the the intake manifold
Wow, I'm sure glad I don't live in California.
Do you have a scanner? Does it communicate with the truck? Maybe the problem was on their end ?
Good luck getting it figured out
If you stop the turbo from boosting I would think you would get lots of unwanted black smoke.
Maybe a better flowing then stock turbo to decrease boost and drive pressure?
You will also need an adapter fitting for the oil feed, it has to thread into the turbo and the stock brass oil fitting screws into that. The oil return may need to be extended, just cut it a couple of inches below the turbo and ad a rubber hoes with clamps to bridge the gap. Just check out the...
You should be able to cut the v band flange right off the back of the turbo and weld an elbow right to that but you will need a 3" v band flange on the other end of the elbow to mate it it to the down pipe.
That could work, you would need a v band flange welded onto it.
What you need to do is measure the outside diameter of the v band on the turbo exhaust outlet. Should be around 4" but you actually need a 3.5" elbow because the inside diameter Of the turbo outlet is roughly 3.5"

That's the turbine outlet. His kit will not work, it only works on the smaller 3" v band flange. Do a search and you should find ways to adapt a 4" tight radius elbow on the exhaust outlet.
Does this only happen from cold starts? Could be a few things. What comes to mind is starting system such as glow plugs, glow plug relay, filters, injectors, lift pump.
Any codes? What year is the truck?
Both can cause the ECM to go into limp mode. The 3 bar MAP sensor is identical in appearance as the stock 2 bar map sensor located on top of the intake manifold. Just search for gm 3 bar map sensor. I got one from eBay and it worked great.
16cm2 turbine housing is not bad at all. Should still work nicley with stock tuning assuming he's got 4:10 gears.
Run a 3 bar MAP sensor till you get a tuned ECM, this way you won't defuel. About 18 psi is more then enough
Well the temps have gone up to the 40s here for the past couple of days and have been getting rain. Yesturday I have taken the truck out and when I would go to use the brakes, the rear breaks would lock up when going slow with just the slightest touch of the brake pedal.
Only thing I can...
This may sound like too much but why not start with an extended cab long bed truck, get a junk yard crew cab and a short bed and put that on the extended cab long bed truck frame. Sell the extended cab and long bed to offset the cost.
This was just a thought I had. I wouldn't even know if the...
