I have had one on my truck all along and am just now starting to play with it. I was only seeing 35 psi boost and 55psi drive pressure with both secondary springs doubled up inside and the stock primary spring maxd out, the boost ref line was split to ports A and D. I emailed Synapse and they said the instruction were for gassers and to not use them...OK...so I put the boost reference line on port B and closed off ports A and D...

45 psi boost and 65psi drive pressure. EGTs went from 1250 previously to 1400 now. Fueling is still pretty conservative.

Turbo is a Batmo S475 with 83mm turbine and .90 housing. The HTT 82mm turbo will be here by friday and we'll see what we can squeeze out of it. but I want to figure this gate out so i know for sure it's not opening
