Hello. Name is Jacob.
Tulsa, Oklahoma USA
I drive a b5 S4 2001.5 Nogaro Blue.
Stage 2 par tuned car with full exhaust cat deletes
N249 bypass on the car.
Water meth w/ 6 gallon fuel cell at 10gph on a 250 psi pump on braided lines.
Stage 3 clutch from vast
I swapped the car to a 6spd from a tip. In my area 6 spd cars are scarce.
I do a lot of work on audi cars.  Love the cars and now I'm interested in learning more about the ecu. I've been reading your site for well over a year off and on and now deciding to post and get some information. Thanks for having me.
