Any exhaust leak will steal a lot of HP from a turbo. Do some searching with a mirror for the backsides of the exhaust in the turbo in/out area. Also look at the area of engine intake from turbo.

Sounds like you don't need to turn the fuel up yet, with those 1100 EGT temps. What you need to do is find out what else is wrong first. I would be suprised to see that high with stock fueling, if nothing else was wrong.
I agree with the previous posts, sounds like you are not building the boost pressure like you should.

well this motor isnt stock its been rebuilt by some place in flordia they obvoulsy adjusted the turbo to run 10 psi says my boost gauge but i have it hooked up thru the wastegate pressure line i guess and they turned the fuel up 1 flat for me cuz i wanted more power and id say i got bout15-20,000 miles on the motor now it seems to be quicker at night when the temps cool down to around 60-70?? i belive the exhaust leak is when it comes outta the turbo

well i had a problem on my leaking y pipe that went in the the up pipe to feed the turbo. i took the y pipe out. measured the opening it was 2 1/2 inches took the y pipe ground down the brunt up flange. took a piece of 2 1/2 exhaust pipe. and pressed it on the y pipe and then ground it down flush with the casting onthe y pipe too a file cleaned it up and then reinstalled it. it had a real good tight fit. and the leaking stopped there.

Word to the wise when towing. Never tow anything except a small trailer in overdrive. The transmission just can't handle it. Even if you have trick the trans out unless it has been purpose built by a shop that knows what they are doing and it has been set up with the right convertor and external cooler.
