is there any thing else that i could do with the ko3to give it alot more power instead of having to shell out 1000 bones for the ko4 and software.
i have a 2001 1.8t fwd 5sp and giac, 710n, and k&n. i really want more!!!

exhaust and test pipe will help. and N75
FMIC might help also

ya pretty much wut panda said. with a k03 you only gona be able to get about 250 hp at the crank. its worth it to upgrade to a k04 IMO

For the price of a FMIC he can get a K04

Here's the problem with 2001 cars. If you go with the K04 and want K04 software, you need to get the GIAC Hammer file (or maybe go with APR--I wouldn't recommend Revo on this car). The Hammer file requires bigger injectors (TT225) ($240), a TT225 MAF (~$110), FMIC (~$850), and a free-flowing exhaust. So, on top of $700 for a K04 and chip upgrade ($150), you're way more than $1000! But...there ain't no alternative for the K03 other than to replace it. I was boosting 20+ psi on my GTI with the K03s, but that was with Revo and outside the efficiency range of the turbo (meaning I wasn't seeing that much more power).

The K04 is a nice, reliable, easy to install upgrade and should work wonders on a FWD car. It's doing great on my quattro.

ya but if i upgraded the turbo i would want to upgrade those parts as well so ur not shelling out too much money. no where near any of the other BT prices. i'd say get the k04 cuz the k03 might still leave you wanting more power. and i think giac gives discounts when you upgrade the chip for the second time to readjust for the k04
