Well... its installed.....
I have a few last ?'s
I installed my sn89 kit on my mustang ..
timing is still 12-14 degrees BTDC ( havent changed it yet )
Plug gap is still .050 stock heat range.....
If it runs good should I still retard the timing???
Should I re gap the plugs and or go a heat range colder and why???
Its not as powerful as I hoped...only making 4.5 psi at 5000 rpm..... It takes forever to climb to 4.5 psi.. I definitely feels faster but I want the most boost I can get out of this little sn89 .. any suggestions (other than a new blower )
