Ok i have a cs3 map.
I know that adding a performance inlet and a cdti airbox on a standard tuned z20let can give you more horses but my question is, can i gain a few more on my map???
when it was mapped it had standard inlet and standard z20let airbox
now i have added larger pipes and the courtenay top hat with pipework, added a cdti airbox derestricted with filter plus i have disabled the rear BCS
could i have gained anymore power???
also im putting a full decat system on it soon...
