truck builds 42 psi boost on stock turbo is this to much? waste gate was plugged when i bought truck.I have done the fuel plate and trans mods myself
what would be the next up grade to do 4gsk or injectors

 

GSK should be done.
42 psi is out of the map for a stock turbo.

 

thanks j-fox should i hook up the waste gate back up or leave alone or upgrade to a better turbo

 

I would add the GSK then drive it like it is until you have the money for a turbo, injectors and delivery valves all at the same time. just remember if you go to the 4K GSK you will need to upgrade your exhaust valve springs. The 160 pump in stock trim won't cause too much damage to anything if you monitor your guages.

 

I'd say run it until you can afford a bigger turbo. The HX is still reliable at that pressure, just not terribly effecient. I did the same thing, turbo was still running just fine when I put my 62mm on. Just try not to bark it from full boost.

 

thanks for the help guys
