you were asking how they mount the top turbo... the exhaust manifold gets mounted upside-down so the exhaust outlet is facing up rather than facing down. My turbo says Switzer on it also and its a HTB2 high tech turbo so yours may or may not be a BD super B turbo, can you look on the small plate on the compressor side of the turbo, what does it say? that might give you an idication of what it really is. also are you running a high flow airfilter? 4" exhaust? youll have to fill out your Signature to let us all know what you have done for mods on your truck and we can help you more!
Welcome to the Boards!

 

I'll look and see if i have any plate on the turbo, altho i don't think there was last time i looked, i can be an idiot some times

I'll go tinker with my sig now, If i can find it !

 

Are you sure about that? I've got one on my truck,and my fuel mileage is terrible too,I guess I'll pull mine out and see if it improves..

Anyone know if an overboost code does anything other than trip the CEL?

 

Yah, i noticed at lease 6-7 Lbs more boost, cause the ECU defuels at 30psi,

But like i said, it ATE my milage, altho the lie-o-meter up top said 20 MPG, i was getting like 12-14, which is 6 below my average.

 

Thanks man,I'm going to unhook mine,I got pretty good mileage,then something happened and I got crappy mileage,think maybe it's that boost fooler...

 

i run a boost fooler and im still kickin like 18-19 per gallon
