maybe off topic...but i recently put a TD05 20g on my 04 wrx 2 litre....i dont notice the lag to be honest...im sure there is a difference from stock...but the power is so much....when i got WOT in 1st i cant shift fast enuff to keep it from hitting fuel cut....i will be going to a HTA 30r .82

. axis block and ppgs as well....course my clutch doesnt hold the power if im in 3rd, 4th, or 5th right now...nothing i can do about it yet hehe
