Yes, I got the hop-up package for $449.
I am mistaken, it is 1/2" out to far so I need to modify the firewall to achieve the 1/8" This is my first with that type of thing so would you mind walking me thru your recomendation to reset the firewall?
Thanks,
Frank.

If the appearance of the gap between the spinner backplate and the front of the cowl bother you, then go ahead and move the firewall.
However if it isn't too bad just leave it. Thrust and cooling will actually improve with space between the prop and the cowling.

Frank,
Check your CG before moving the firewall. If it's OK then I'd put the engine on and fly it. I spent a bunch of time movng the firewall on my Yak to reduce the gap ... hindsight being what it is I'd have prefered to spend that time flying the plane. It's not a difficult task, but one that is tedius to keep the correct engine thrust angles.
