Tuned it on a friend's dyno here in Cork (Fionnsport)
Finbarr has worked at BMW and VAC so not many about that knows his away around them so well

I've a standalone ecu but I'd recommend going th CSL tune route rather than Alpha N as its much more refined.

Iv heard of Fionnsport, was actually going to try get my e30 318is tuned there (once I get it back).

Yeah I keep hearing theres a big difference between the CSL tune and the Alpha N. Would defeinitely prefer to go CSL tune route. Good to know Fionnsport can do it.
