Cool 38r & high egt's

OK I have a 2002 with intake and exh mods with a TSchip and recently installed a 38r turbo. I was expecting lowere egt's but they are the same as the old turbo? If from a dead stop I go all out I have to shut it down at 55mph because egt's are at 1250, is this normal? I have checked the up pipes and intercooler for leaks but didnt find any. The turbo has a 1.0 exh housing should I go to a 1.15? I also left the ebpv inslalled. Or do I have another problem somewhere? My boost pressures at 70mph are 1-2psi and at full throttle are 28psi. Any help or sugestions are greatly appreciated.

Get the 1.15 but also get some good custom tunes a 4 inch tb exhaust will also help if you don't already have one

Re: 38r & high egt's

Somethings leaking I bet. Check your up pipes, boots and manifolds. I think dieselsite sells a kit to check for leakage in the intercooler system, or make your own for cheap. make sure your ebpv is open all the way and isnt partially closed.
With stock sticks 28 seems a little low.
I wouldnt go to a 1.15 unless you have upgradded your sticks to stage 2 or above

The 1.15 isnt going to do you any good. I have the 1.00 housing on 38r on my truck and dont have any issues and I have big injectors.

Get some better tuning. With Matt's tunes from Gearhead on the daily driver setting i cant get it to over 1150 degrees.

Get him to reburn your TS Chip you will be MUCH happier

28 psi with stock sticks is not low at all. Its about right.

Re: 38r & high egt's

ya I already have a 4''dp, and have checked everywhere for leaks excpt the compressor housing. will check the ebpv and do some checking on a custome burned chip. Also when I bought the turbo it was used and it didnt come with a wastegate acctuator so I used the one off the stock turbo is that something I would need to change? Thanks everyone for the replys

Re: 38r & high egt's

28 psi on stock sticks and a TS chip is about right.

However, with a 38R and stock sticks, you don't need the wastegate to open up. Take your actuator and tighten it as far down as it will go. You can also wire it shut by wrapping some wire around that wastegate arm where it attaches to the actuator, and snugging it down to something to keep it from opening.

Except I can hit 34 psi with mine and stock sticks.
