ko4 with revo software?

buying an a4 with revo stage 2 software. is that compatiable with the ko4 or what turbos will it work with

From my knowledge, revo stg 1 and 2 are both ko3 sw and stg3 was either 380/440/550cc files.  You can do a ko4 on stg2 but since you cant use lemmiwinks/unisettings it would be hard to get fueling right unless you get a wbo2 and tune with a adj fpr which is less than ideal

so then what do you suggest i do?

what are you trying to do?  Are you buying a new car or upgrading turbos?  Your first post is kind of misleading... to me atleast

buy the a4, get a stock ecu, chip it with apr or giac. least that's what i would do if i wanted that car realy bad. otherwise find a different car. 

alright buying a 01 with test pipe 2.5 inch borla exhaust fmic intake evo ms dv and stage 2 revo tuning. in the futrue i want to go k04 maybe larger but lets just say ko4 for now. can i put a ko4 on with that software or do i ahve to go giac what can i do

ok, with a 01 you can install a ko4 on the revo tune and with a vagcom and lemmi/unisettings you can tune it.  But then you would be trading a efficient ko3s for a slightly larger less efficient ko4.  Your not really going to gain much for the money spent.  w/m would give you better gains and cost 1/2 of what a ko4 cost new.

sorry if this sonds stupid but w/m?

water meth injection.  It cools down the intake temps and increase the octane rating (meth is 116 octane) among other things.  This will let you increase boost and/or timing either manually or with a 100oct tune
