Engineers slaved over all sorts of obscure tables to get the tune right, and it's those obscure idle, intake manifold wall wetting modeling, temperature compesation and modeling, etc. Tuning requirements will be minimal and it's far more robust and sophisticated than aftermarket computers. ![]() Stock ECU is not only easy button, but best button. If you see yourself going down the rabbit hole, Terminator X Max. While I built the engine for 22psi boost, I imagine I will be too scared to even approach that, much less need meth injection, on a street-driven 60-year-old 2wd pickup. It starts adding to be almost on par, but as mentioned above, it's going to depend on how serious you want to get. BUT, it comes with a wideband, can serve as a boost controller (which would be $600cdn), meth controller ($400cdn), and traction controller (?). The Terminator X Max setup in DBW and trans control will set me back $2000cdn. Add an electronic boost controller and Meth injection and it starts adding up. Add to that a wideband for $300 more, and I'm in for $825CDN. HPTuners will set me back $525CDN for the kit and credits. Since I'm still intending to run a stock cam, keeping the stock tune (just scaling it to fit a 2 or 3-bar VE table) makes sure I maintain all the perfection that GM provided as far as economy, cold start, driveability, etc. In my '61 Chevy pickup I have an '07 LQ4/4L80E drive-by-wire pulled from a van, to which I've added a 7875 turbo. ![]() Interestingly, I am in the exact same boat.
