Another vote for the 8374/1.05 especially on a smaller 2.6L.
The OSG triple is a pleasure to drive. The pickup point is lowish, not grabby/bitey. Having had a Nismo coppermix for just on 10 years, I was quite hesitant about going to the OSG triple. Totally unnecessary.
* Apprantly they did some changes at some point. Not sure when the change over was but it would have been before July 2015.
