Looking to see if anyone has put a vertex performance chip on there 85 4 runner need a diagram or instructions on how to install correctly

 

Never heard of it but a shot in the dark this is a mixture tricking device that changes the signal from the vafm.. It's a stupid hack device and you're not going to get any big/noticeable gain in performance from the ~90-100hp engine. Worst case you burn up the cat from running rich, or burn a valve from running lean.. To can mimic both of these by adjusting the vafm clock spring and not have to hack your wiring.
