There is no way you are going to get 30+ hp with the upper charge pipe? How did you arrive at that number? Thats SII right there.
Even though I installed SI, the amx turbo up pipe and plan on installing a 3" down pipe there is no way we are going to realize 30 or 40 more horse power with the PCM controlling the waste gate. We may optimize the stock or SI pcm with our mods but unless you bypass the PCM control of the waste gate you are not going to see these kinds of gains long term. I do believe that SII is the only way to improve part throttle drivability(if it is different than SI?) and is going to be extremely mod friendly with pleanty of juice @ WOT to boost our little hearts out. The only problem will be reliability and longevity of the engine. I am talking about head gaskets, rings, pistons,bearings and valve train components, things are going to wear and break. The more you blow on these the sooner they break. This is all part of going faster so be prepared the pay the price, something else you may want to consider.
