there's more (alot more) from several knowledgeable sources to be found H E R E

with the stock turbo, and a pre-existing tune that's correct, i'd imagine you'd be shooting for about 1 hour (total) dyno time to get this "finetuned".

the best thing is that JP will directly work with you on this and is available to help you or whomever....

good luck!
