I think your suppose to install nsbu switches with the trans In neutral. The switch is in the neutral position out of the box and I think that is what it calls to do I'm not sure if it makes a difference but that is how I've always installed them
Waste gates are necessary in most compound kits without them you would have high drive psi or a slow spooling kit ( loose A/R housings to keep drive psi down) is my understanding.
No I ended up switching to a GT55. But I'm in the middle of dropping a 106 GT55 wheel in the PBK it has been a lot of work but it is almost done and we are going to try it on a friends truck as a atmosphere charger I have high hopes for it! Should be a beast of a charger.
I'm fine with people not believing I really don't care I was just giving some advise on other ways that might help with the hg job and if this is how people act for me trying to help you all can go f**k your selfs
We have ran a 75 and a 80 against the 83 billet and we could not feel a difference in spool between the 80 and 83 billet this was on a cr cummins as a single. I think the 83 would be just fine
