Not really any options that I would recommend. I've tried a few and really no-one comes close to the obvious gold standard - having SpecialtyZ tune all my cars when they were in Edmonton. Here is my experience: Dealers: Calgary dealers have forgotten whatever they once knew about these cars, and are pretty disinterested. The Edmonton guys seem to have better luck FWIW. Reg @ RCTS: Expensive, doesn't do a lot of Zs, wants to sell you a standalone, no wrenching (electronics, tuning only) Autodream: They will get you running but my impression is that they rely heavily on the fact that a z32 can take a lot of pounding before it actually dies. (I haven't talked to them in a couple of years so things might be better now). Nistune: I spent a lot of time with Nistune before having SZ do my cars. It is a great DIY tool if a) you have the ability to datalog on your car including b) onboard wideband air/fuel , boost levels and temperature levels and c) time, patience, discipline to drive, datalog, make small incremental changes, read, research, make small incremental changes, repeat. Personally I think that optimizing a car under real driving conditions in addition to dyno tuning is a smart idea but it is very time consuming for the DIYer. DIY: Finding a boost leak and installing a dual MAF is not very difficult. There is plenty of info on this site and there are a few locals like myself around to help if you get jammed up. (Disclosure: I am NOT a mechanic and I don't "work" on other people's cars, but I have learned some things through years of ownership and can lend a hand on most of the systems on these cars now). Bottom line: If you are going to own one of these cars nowadays, you might as well consider boost leak testing, intakes, exhaust, plenum pull, injector change, clutch, 120k etc as "basic" or "minimum" skill sets IMO, (assuming of course that you have some basic tools and a place to work on the car). Sorry. Hope this helps.
