AEM has traction control standard.. why not use it? Also, why would pump gas cause you to surge? 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!
