What did they change in the tune? Redline? Not much to account for airflow wise as I dont think there is even a function to do so?
Not for sure on exact changes. Redline moved to 7800 more ignition timing and some cam timing changes

Did you lock out?

Anyone have a write up? I can’t get into the fb group :(
If you are just going to lock out the imrcs then you will need a way to do that. I left all the actuators on mine because the default to open and I'm still trying to get them to work. My main tune has them turned off but my tuner is trying to work the bugs out to make them work. Just takes some time due to my schedule. As far as adapting goes you will need some 3/8s vacume line to adapt everything over. Which is the line for the break booster and the evap purge solenoid. And if it is a 15-16 you will need a vacume cap to go on one of the ports of your cold air. The vacume line that runs down the inside of the driver side of the old manifold goes away.

I wonder if it is possible to wire two plugs together instead of trying to tune one out. Does anyone have the wiring dit for the two other plugs that don't require pigtails two compare the 15 to 18?

I heard that we need 5/8” pvc line to adapt it all over. Is this true, or is 3/8” the proper size?

I just installed a 2018 manifold locked out along with Pro-charger stage 2 D1SC head unit, Sai Li return fuel system and left my Comp stg.3 cams in place. Hopefully should all be together and running by the end of the week. :headbang:

That's what's up! I'm looking at the D1sc and vortech jt. Would love to see your numbers with the stage 3's boosted
