From what I've seen, Richard's 34 seems to go Hard as does Kasko's 33. (as witnessed at Goulburn 2012 Nats)
You already have : Cooler and Exhaust so you have more power than stock.
Your whole "Gentleman's agreement has suppressed my vehicles potential" argument is null and void as a result...
Are you truly capable of handling what you have now? I don't think you have scared yourself yet...
You will gain a greater appreciation when you do. This trackday thing you are going to do might just be what you need.
But it's your car and your choice.
Personally I "think " I will be happy with my retune on the SAFC... at least for the moment.
The low throttle response is so much sharper than before and if I can achieve an extra 20-30kws it will be awesome!
If and when my Turbs pops, I will defo get in touch with Stao (Hypergear) and get me some hiflow. ($1000)
But only really as a rebuilt reliable replacement. I can't see myself upping the Boost, upgrading injectors etc...
As you know, my car is my daily and all I really want from it is Reliability with some punch but not at an extravagant price tag.
But as I said, it's yours to do as you please, learn and make your own decisions / mistakes.
As for being quicker than me... my Auto diff helps with acceleration.
You will Never have me as you will Never have your Car.
