I am thinking of havng a Unitronic Chip installed in my 2005 4.2. Anyone have any experience or knowledge regarding these chips? Unitronic claims that it increases the output to 355hp/329lb-ft, which is an additional 20 on each over stock. There are two authorized dealers on Long Island, Tyrolsport and Force Fed Engineering. I have heard good things about Tyrolsport, but Force fed Engineering is closer. Any experience with either of these two shops? Thanks.

 

ive seen a few people around with force fed stickers on their cars, i know of one guy who had work done there and had no complaints. never heard of tyrolsport.

 

Force Fed knows what they are doing. im good friends w/ the guys that work there and i would only trust them to work on my car performance wise. they work fast and do it right. I dont have their unitronics chip yet but as soon as i get the $$ thats what im gettin and thats where im goin.

 

what part of long island, thats where i live. only audi dealer i know of is in smith town

 

did you get the unitronic chip on your 4.2. I read your post in 2005 and wanted to know if you think it was worth it and if you felt the results. Also, what does it raise the rpm too?

 

I have 49K miles, so my Audi warranty will expire near the end of the month. Once it expires I am going to try Unitronic.
