Surging means your FI system needs some reworking, either unproperly chosen turbine, or piping that cuts too hard. Or the waste gate just dosent open enough to control it. I've also seen lots of single turbo supras that need proper blowoff's like a greddy type R or at least 2 HKS SSQ's and they only have 1 normal BOV ( single SSQ or something) and they stall.
Now away from the annoying questions.
I really hope you can get another road racing supra out there. Its a REAL rarity to see a supra on a circut in america. GOOD LUCK, I honestly mean that, I'm rootin for you! 
I understand aem had some provisions, but ive heard everyone doesnt want to use it.... they have problems getting it to function well, without killing power and or not stopping spin.. enough on that, ive also heard the BL71GTQ surges frequently on pump gassable boost levels with a good fuel system, twin stock pumps, 2 feed, 1 return and a set of 1000cc injectors. Im not sure why, but i suppose it builds boost quickly enough to do some damage at 18 psi - granted this seems to be people with cams and some head work as well! I have a tial 50mm bov, and plan on adding another for good measure on the other side of the intercoooler piping when i get a chance
Wastegates are typically very good, HKS GT2 gates, 60 mm gates, used on 1000hp cars that see little to no spike or creep. Lots of the turbo kits do take a sharp 90 right out of the compressor, but thats the easiest for routing, and seems the most common... Surging seems to happen on a lot of the moderate turbos, from 67's to 74's from what i hear, although im not sure i hear too many people with problems on the larger side of things...
thanks for all the input, ill let you guys know whats going down then
