Dave and I had my 2000 Audi S4 chipped at a high perf professional shop and it went from 250 to 318 HP! Wohoo, that twin turbo could scoot and move those Bridgestone SO3s! ......'course it cost about $1,100. Ah, fond memories from long ago and far away!!!!

When I saw those $25 ones offered on ebay I just had to laugh, knew they had to be a scam!
