Here's some additional positive feedback on top of what I had up previously, as some of you know I had a cam done through a place here in Adelaide, from day 1 it was far from perfect despite additional attempts at fixing it, with numerous problems ranging from idle all over the place (I know this is cam related but much worse than that), wanting to stall on take off, a real bitch to get started again after a short trip ie to the servo (it would stall and then wouldn't refire, I had to resort to using the accelerator) and in general shocking driveability especially on light throttle applications ie trying to keep with the flow of traffic. To summarise it really took a really nice car to drive and made it felt like rubbish to a point where I was considering getting rid of the car all together.
Anyway Steve noticed a thread I had put up and offered his assistance, after failed attempts previously from the other place I gladly took his offer up and started logging away and describing the problems. What made it very difficult was the fact that the cam specs weren't let out of the bag as they had excellent results previously (I beg to differ on this one) so basically had no choice but to tune it blind (a mighty feat if you ask me!).
Fast forward a few days / weeks working with Steve in between my own work commitments interstate its now to a point where I could only describe it as perfect so many thanks to the guys at MACE, they say you pay for what you get but considering the price, understanding and complete support day or night I certainly wouldn't go anywhere else especially considering what other pricing points are out there.
As a bit of a side note fuel effiency, lets face it you don't buy a V8 to be concerned about fuel prices or how much you go through but I have noticed since having the revised tune done by MACE the car is averaging 1.0L - 1.5L better off in my daily travels.
So in short a big thumbs up and thanks again to Steve and MACE
Cheers
