Good evening 79vette,
My car left Spirit River in early November, trailered to Edmonton and by train to Manny.
It has been an interesting adventure and I would do it all over again. Manny seems to have a very powerful package for C6 Z06's that give over a 40% rwhp boost when all is said and done.
While you can do the work yourself that is not an option for me and I looked into a few places in Edmonton and Calgary. Sadly the attitude out west seems to be that anyone who owns such a car is an open wallet (sort of my ex-wife's attitude too, thankfully that was before the Z06!).
What impresses me with Manny et al. is not only that they do the work but the, art perhaps, that they put into the work, the small attention to detail that they bring to their work.
You can't end up but feel that your car is in the best possible of hands and that the outcome will be of the highest calibre.
I'm looking forward to both going to get the car in the spring and the pride in having a Dasilva Motorsports modified car. Sort of like a RUF Porsche maybe.
I had been struggling with the same issues you did in terms of finding someone local and in the end, even after shipping costs, the package was going to be less expensive and a higher rwhp gain than going local.
If I might advise, check out the cost of having Manny do what you would like and then the cost of getting the parts yourself plus having to find a local tuner who might be worth risking leaving your car with. You might be surprised that Manny is a good deal more competative than you might think and you are getting a one-stop deal that you won't get anywhere else.
Cheers,
Garry of Grimshaw
