i cannot remember who for the life of me but there IS someone gettin around on here with quad throttles on their 2tg, i'm pretty sure using the 20V ones.
im pretty sure hes using a setup from injection perfection.. i may be wrong? i got quoted from them $2500 alone for a quadthrottle setup on a 2TG. Im pretty sure using 20V throttles will be ablt cheaper to setup..
