Sadly i sold it to a sucker on ebay hehe, I got my custom 93 tune a month after taking off the spacer also, so first i will go back to stock for awhile and run 87. I have also found another problem, often i find that my air filter has fallen off
it is on very tight yet manages to come off. I'll have to wait and see. If nothing changes i might have to go back and find a used spacer to see if that really was the trick.
