Running Accufab 90mm TB without a spacer??

block off the EGR coolant lines, run a resistor to tell the computer the EGR is working(not sure the specs, someone hopefully will), fab a bracket to hold the throttle linkage and that's it I think.
 
IDK its up to you really. If its not a DD, and from judging by your sig it isn't at all, I'd just leave it off. If budget is a prob, also judgin by your sig is not a prob, so maybe you should just by the spacer
