ph1 172 Running lumpy

[*JimmyJ*]

Recently I've noticed that my car is running abit lumpy and it doesnt rev freely too 7250RPM. Stops at the first red dot. Do I require a Remap to iron out these problems. And how much will it cost me?

Its a ph1 172.

A good service would be a better place to start imho.
