Well the starter of the thread does (Power FC), Sasha at SG Motorsport (Power FC, AEM) has tuned some good cars as well. Then there is Neetronics in Mississauga (AEM, Hondata, EcuTEK, MoTeC) tuned all kinds of cars, also had my DSM done there.
Couple semi-private referral tuners Magnus Motorsports (AEM, Haltec) and Ultimate Racing (HKS FCON VPro, e-manage)
Personally, I’m going with AEM. EMS is more common, there is great support and we’ll it found +44whp out of a bone stock RB26DETT which is unreal. Plus the interface with all of the other AEM peripherals is perfect…it just does everything.
I used to have Power FC but sold it since they discontinued it…currently running a Central20 ECU from Japan
