boost numbers after new turbo

Should I have the same boost numbers while cruising after the install of a MTW stage 1? Reason I ask is I'm having a few symptoms of a boost leak and I have noticed now that my boost while cruising 70mph has dropped about 2-3lbs. Only additions have been the turbo and 175cc injectors. Is the turbo that more efficient or is it bleeding off somewhere? If it leaking I can't tell where. I'll have to do some more searching.

All the above just to haul the 900hp street mustang

get a tuner to close the vanes slightly. it should cruise around 5-6 but normally stock turbos will sit between 8-10 at 70 so maybe you do have a leak

I'm running Matt's srl and my stock turbo did run about 8-9 @ 70 and the stage one is at 6-7 @ 70. My other issue is my gets have increased slightly, from about 760-780 to 830-850. That's what originally caught my attention. My peak boost is the same, 26 but my gets rise much fast and go much higher. Maybe it just come with the territory, maybe I have an issue

Not to sound like a jackass but did you get the tune written for the stage one and 175's? Or your stock setup?

egts sound about right to me atleast. maybe they can open the vanes up. i know thats backwards from what i just said but reading your last post it should be around 5 or so which with opening the vanes a tad you will get that and it turn it will lower the egts slightly if at all. the powermax which has no power compairison to the stage one but when swaped from the stock turbo will have slightly higher egts as well

Matt said the srl file should be fine for the new additions. My 175s have stock nozzles, he said he shouldn't need to change for stock nozzle. Also after talking with Adrian he said there should need to be any tuning adjustments for a stage one. Just to verify the tune wasn't the culprit I had tony write me a file for the 175s and the stage one. I'm having roughly the same results. Obviously the driving characteristics of the two tunes are different but have the same get issue.

Matt is wrong. A stage1 is not a stock turbo and requires tuning to get the most out of it as you can clearly see. The vgt vanes need to be closed slightly and open up slower.

What you have going on is a common problem and is likely the tune. Same thing happens to me when I go up in turbo size. Say from stage 3 to stage 4, my boost a cruise 70mph would go down do to the flow of the turbo being much more. I believe you have the stage 1 with the billet wheel which is a whole different turbo from the cast wheel one. Either way check all your sensors and then leaks if none found you will have to get the tune adjusted. The reason the egt's are slightly higher is because you are not building enough boost at 70 mph to get the air in the engine. Ideal boost is 5-6 psi of boost at 70 mph which you should be at about 2000 rpm. Common problems is the hose from manifold to MAP sensor, the other is the y pipe not seated. Keep me updated and remember that the ecm will need to learn where and when it needs to adjust the duty cycle. Putting a turbo on with more flow isn't slap it on and go on the 6.0, ecm has a lot of input so needs to learn.

I will ask him about this. Also the be fair I'm having the same issue with the tune from tony that I had written for the stage one and injectors.

I will forward this to matt. My cruising boost at 70 prior to turbo and injectors was 8-9 and egts around 760-780. Boost is now Lowe, 6-7 and egts around 830-850. This is all at around 1800 rpm, I have 37" tires and 3.73 gears. This could be why I need more boost, not enough gear. Thanks Adrian, I'll keep you posted
