great fun, and i didnt break anything! i was really amazed on how my TD jetta did, with over 300,000 miles, i was expecting around a 21-23 sec. 1/4 mile, on my first run with stock fueling and blow off blocked, wastegate turend in, around 15-18 psi -keep in mind i havnt been to the strip in 2 years, and never raced my diesel before, i ran a 19.594 @68.14 mph, pretty slow, but better than i was expecting, next run with stock fuel again was a little better with a 18.678 @69.68 mph, then i turned up the LDA 2 turns and main fueling 1 turn and ran a 18.383 @71.17 mph, not a big difference, but i even beat the civic i was racing, good feeling! then again i ran even better with a 17.674 @73.04 and beat a new toyota carolla S, but my best run was my last- 0.09 R/T and a 17.591 @73.53, really impressed by that one with boost hitting 25 psi, first for going that high, and since i dont have my egt hooked up yet, i decided to call it a night before i broke anything, but it was cool to hear the ppl cheer when i launched and a cloud of black soot covered everything behind me, i really thought this car felt a lot slower, its accually 1 sec. faster than my old mk2 jetta w/ a 8v gasser and 5 speed close ratio gti tranny, cant wait to see what it will do w/ the new motor, giles pump, pass. perf. downpipe, GTD nozzles, lots of port work and a intercooler which i will be starting on soon, once i sell my audi on ebay!
