they are done, put 100 miles on so far, runs good insane turbo noise and quieter exhaust
making 32psi up from 23, 9psi off the big charger and 22 off the little one with 0 lag
30-100mph wot max egt's 850*
this is on a approx 50whp tow tune
just set a check engine light though.... thinking maybe maf related since its sucking way more air now... did it after about 100 miles
does this sound right for check engine light???

:nopic: thats awesome man i really like how quiet the twins make the truck it was a added bonus , i have never ran a tune that small on my twins that is crazy on the egt's congrats man
MAINER- NICE TALKING ON THE PHONE TODAY, I WAS WONDERING WHERE DID YOU MOUNT THE MAF AT? YOU DID MOUNT IT PRE big TURBO? take it out and clean it with brake cleaner or better with maf cleaner in a can
I don't know if you have done it or not,but I would get a Super Diesel intake horn for that factory turbo and reduce the restriction and help it flow better.
So you are only making 3 additional pipes. An pipe that goes where the old down pipe use to be to the new turbo. A pipe from the new turbo to the stock air intake on the stock turbo, and then a new down pipe to line up with the exhaust under the truck.
Then there is always the optional hood stack. :rofl:
Anyway one more question. If the stock turbo blows at 3X pounds of boost, then why is it fine when there are dual turbos?
I think the turbo can only take so much pressure differential, but I am not sure.
Sorry for all of the questions.
BTW does the intercooler have to work hard with 2 turbos or less hard? I know twins generally help keep EGT's low, but why?

where did you put the maf? if should be before the big turbo. some trucks dont give a shit where the maf is and some do.
THE STOCK TURBO will only push what the wastegate is set at(20-22psi max) and the larger turbo puts out 25-30 psi . so you are not overspeeding the stock turbo
Nice job mainer .......... I cant wait to hear these things . I hope you get the code issue figured out .
But since all the air goes through the stock turbo wouldn't it overspeed?
It is very confusing to me it seems like the stock turbo would be a big restriction to the airflow of the system
The stock turbo has an internal gate. Unless he did something to make it inoperable, he's still running a gate on it.
