Ok the results are as follows. AFR is sitting very nicely on ~12:1. Its putting out 250rwhp almost exactly which for you guys who use kw is 186.4rwkw, this is with a farked cat too. Its running soooo much smoother and i can already notice a difference in the economy just from driving around last night.
One minor thing is the aircon. Just need to bump up the RPM a couple of notches for when its switched on. The guy that tuned it came with me for a test drive which I thought was fantastic. It will be going back early in the new year just for some fine tuning and replacement of the cat, see if we cant squeeze a few more ponies out of it. Im pretty confident it can be done.
So final word, very happy with Mercury Motorsport, could not rate them enough. Trent is a champ and is an excellent face for the business. The guys down there realy seem to know thier stuff. Pricing is good and is even better with SAU member discount. I will definately be going back there in the future.
Cheers,
Steve
