To all of you who have modified your 172s, whether Cups or not, and primarily relating to power-enhancing modifications, eg chips, pipes, and intakes.
a) What have you had done?
b) Have you NOTICED any improvements, or indeed any decline in performance? AP22 before/after?
c) Have you got rolling road printouts/figures?
This might seem a pain in the arse question, but to anyone who is thinking of modifying their car, nothing compares to personal recommendations or advice. I have already had some ace advice on brakes etc from some of you, so keep it rollin!
Cheers!
