    Currently no one offers a real tuning solution for the 90-95 4.5L/4.9L V8.

    There are a couple hacks there for speed limiter, but I think that is about it. It isn't as easy as most think to do, else it would have been done.

    Call Lyndon Wester (Wester's Garage) and see what he can recommend.
