I had my standard 1HZ cruiser turboed by Mike vine about a year ago, part of the installation was to give it a good tune, all the other performance aspects of the motor not directly related to the turbo was also checked, much much better off idle even with no turbo boost it even starts better, there was noticeable difference, I will most certainly go back when tune time comes again, I'm not sure what he can do for you
In the nearly 12 months from the instal I have had zero issue and only have had to ring him once and that was to thank him for a good job.
My cruiser tows my Jayco swan OB with the wife and 3 kids and mother in law fully loaded up Toowoomba range in 3rd, It was pushing the limits however with temps, but from a performance point of view it does it quicker now with van on loaded to the hilt (close to 5 ton) than it used to by myself with the cruiser empty.
I found Mike to be forthright and honest, he's price was at the dear end of the scale but I the feeling I got was I'm getting what I paid for, with 12 months retrospect, I'm still happy,
My fuel economy did slide when towing, but is the same when empty running, and now to have the ability to overtake to boot.
Thumbs up for Mike from me
