I didnt read anything over 43 psi with my juice w/att. I swithched to the ADR and now I have 60psi with a litte more but I havent taken it that far yet.

Been out beat'n on the truck for the last hour and can get the truck up to 43-45 psi. Is that all I'm gonna get? I still pull a 30' trailer, will I be able to keep the pyro in check with that hooked up? I thought when bought this the pyro would go down but haven't seen that yet, any thoughts.

I've been reading some old threads and wondering do I have enough fuel for these turbos or should I be going back to a 62 of some kind for better all around use. These turbos have all kinds of big end but seem to lag a bit out of the hole but maybe that is normal I do not know.

what sizes are your turbos?

you may not be able to spool them real hard on the top because of your injectors. I believe the secondary is a 57/12 and the top is a 66 or 68/12

The turbos are a b1 (s300) and a b2 (s400). How big of injectors could I go with and still a able to tow 30000lbs gross?

I really dont know. Some 150's may do better but I cant promise you. Too big and they will be really hot but if you dont spool them they will be hot too.

Is the B1 wastegated with a boost elbow installed? If so trying setting the boost elbow adjustment about 1/2 turn open and try that.

How are you reading the BOOST????
If it is through a box, that read from the factory map sensor, I have heard it won't show over 35-40. Get a new guage and read it.
You may have higher boost and it isn't recorded!!!!

I didn't know that the MAP would do that I will get a regular boost gauge in stalled and see what is going on.

My TST would read up to 60 psi.

Well, maybe my source is wrong.
Interesting to see you guys can read higher.

well i have a question? I dont have twins although I would like to eventually but , I do have a superchip plug in box (older one) and my boost guage will hit 30 psi if I really get on it, I am wondering if my guage is reading correctly , I have it tapped right into the top of the intake near where the heater grid is (well about 8 inches away)it seems legit but now I am wondering
