12.7 DDEC4, get rid of wastegate?

that's awesome.johnny

 

I just replaced my OEM Garret turbo with a 171702. Dam, it was cheap enough for sure (from Truck Pro) and very straight forward to do.

I have a tune on my 12.7 but not sure it was done as good as it could. I am replacing the CAC this week and then will do more testing.

yesterday I saw truck with bad WG cylinder, bad diafragm and WG wont working. No fault codes.....

 

i have a 12.7 500hp ddec III. Would i also use the 171702? How about the s400-75? Needing to replace manifold thats leaking at the joint from center section to right hand (front) side. Thought might do both now. Current turbo don't have waste gate. Not sure what turbo on it now. But its garrett

 

The 171702 has the 75mm comp wheel. It is a superior wheel than the Garrett.

 

Thanks for the help.
The only real differnce in the IV's and the III's is the software, right? Once I get the motor up to specs and really liking it; I should be able to tune (turn) it up just a tad, right?
