Whats the best way to improve the HP on the A4 besides the GIAC Chip?
and whats the most HP you've seen in a HP

 

man i got the APR chip for my 01 A4 dude and i got the 93 octane chip and got 44 Hp/81 torque and i spent jsut a lil over 500, but an exhaust can give u HP, i mean i got a custom exhaust done up, so i am hopin igot over 10, wit ha custom cat back, but the chip is the best bang for the buck man

 

after chip, a test pipe will probly give you the next best gains. most hp i've seen in an a4- something like 800hp. most hp on stock k03 turbo? like 250 chpis probly the max, and thats with like every supporting mod including meth injection. unless you add nitrous of course lol.

 

yea best and quickest is a GIAC chip

 

how mnuch does K04 Turbo Upgrade Kit HP add?
