About a month and a half ago i did the infamous diode mod on my other wise stock 03 and its had is benefits and downfalls. Ill start off with the down falls; to this day the car will sometimes feel weak and kinda sputter at 3k to 4k rpms, then take off fast to 5500 rpms. I also was receiving a code about a pressure drop between turbo and manifold that i was just clearing with vag com. it has gone away and not been back for a couple of weeks now. on the other side of things the car is much quicker. stock i was 8-9psi (most say thats too low for a b6) and now im right at 16-17psi. i can actually hear and feel the turbo which is an added bonus. To date i have made no tweaks using lemmiwinks but plan to do so to increase the boost to 20psi. im currently in the process of getting a hold of vag com to check out the air/fuel and timing pull, but im still learning what to look for.

on a side note using my buddies iphone dyno whatchamajig said i got a 6.0 and 6.1 to 60. could that be somewhat accurate for a 2003 1.8tq 5 speed at 17psi w a k and n drop in 100* heat..??

any input, questions, advice or knowledge is appreciated.
