Running 2012 procross with td 4 stage and getting 15 to 16 lbs on power trail and 17 to 18 lbs on max 91.....this seems low to me.

Doesn't seem low to me, 18lbs on a 91 tune is great. Max is 260 right?

Low numbers. Could be anything from boost leak blow off valve leak, or simply bad boost gauge or a wastegate issue etc...

How many grams in the primary and what RPM are you running on each program at full throttle once it settles... don't give me a recall number I'm talking about what it runs once steady for RPM.

running t1s with the two smallest inserts in the heal....will have to check how much weight that is.
The rpm is a concern it starts out about 8100 or so but drops to 7700 or so as you cross the lake.... This is on max 94 it's a little less rpm on power trail

You should not lose RPM with no tip Weight . Check all boost hose clamps and make sure your boost lines to selonoids are hooked up correctly

Went over all the clamps last time I had the hood off but will check again.
what should the boost numbers be?
The rpms drop as the run progresses......I don't think it could be boost adjust because I don't get a light

That should work. What are you running for a shim? Should run DDSA2 or D&D Z1 Turbo shim.
