The first thing I did was Google the phrase and got the usual embarassment of riches and thought that tapping the knowledge base here was a good step. I have an email out to a company in Oz who has modded a X5, in answer yet.
She is pretty well adapted to a left foot throttle and makes funny faces over hand controls.
It's been a long time since the dyno room days with Thinwall Fords and the last serious wrenching I did was a small block Chev into a Toyota Land Cruiser. I know from Double Pumper Holleys and cables but thought there might be something about the throttle set up on X5's I had better find out about before I went down the road too far.
The days of fabbing something up in the shop are done. Nowadays I want to buy a solution and say, "Cause it to be done.". There's also a logistical question in that I'm in SoCal and she's currently in Houston and the car will wind up there, Austin, actually and I'm still researching dealers down there to deliver it and am looking to get the whole package put together. I'm kind of a belt and suspenders guy who likes to have all the ducks in a row ahead of need.
