run max 22psi with the std turbo to avoide any reliability issue.
mind you the efficiency cfm of the td03hl turbo is still producing good flow up to 25psi.
run 22psi and you will get the best of both worlds, very good reliability with a big sweet spot flow of efficinecy of the turbo to produce the best numbers and best feeling for all you gents.
as for the carbon build up, remove the small rubber tube connecting from the engine to the intake pipe.
then fit a long hoses, and just bypass that down to under the truck so it gets thrown away.
next, close your egr. you will also gain hp and torque, as you can imagen instead of air with carbon being intaked in to engine you just get plain old good air

and everything will run much more efficent and will last alot longer the std to.
if u want i have a picutre of the egr plate you should make if you want to close the egr. it might help alot of people in the forum.
