take it easy chap, most of us are here to help, and many of us have trodden this road before.
Getting power out of a TT is like squeezing water from a stone, like money from a tax collector, like boys from micheals hand....
Pretty much there is a limit that you can get to easily. From there, the next logical step is to drop a single turbo onto it.
Things to do/look at to get to this first turning point from stuff you already done
Make sure AFM is braced!
Walbro - insurance
Rage downpipes (HUGE difference), may need custom y-pipe. - Best bang for buck
Zerosports sequential controller - heard good things
Apexi AVC-R - def a good thing
After that - you only really have the little things left, like brakes/looks etc. Unless you want to really start getting reamed over prices, where a single turbo will be by far the best choice, as tuning/finding aftermarket ecu's etc is not going to happen.
Nevertheless, CS is full of people doing 'the unique thing' just because they dont want to follow the proven track for speed, if that floats your boat, go with it, just dont get snarky when people suggest otherwise. There is a reason they are suggesting that, and its NOT because they want to make you miserable/wind you up, its because it WORKS.
Also. Numbers generally are only for show ponies. The major difference is how it drives/feels. For example. im putting some equal length headers onto my car. This will likely reduce my overall power, but has a huge increase midrange. Much more useful for pulling out of a corner, than the 10kw at 7500rpm.
