I've got a 2009 too. My plans are dp, upgraded tmic, injectors, pump, tune. so far I've done an AP tune and am up 33hp from stock. the dp should get close to 300hp.

Injectors and pump for reliability. 268whp is at 88% IDC for me, so 300whp would put them very close to max. Possible to get 300whp with stock fueling, but not reliable.

the tmic serves two purposes 1 its stronger than the stock plastic that can hold anywhere from 18-22 before breaking depending on who u ask and 2 it can help compensate for running the turbo in a lower efficiency band in the higher rpms.

I wouldn't expected a modded car to be very reliable. just keep some money in the bank and order performance parts when the stock parts break.
