Yah the lines are a bit bumpy, and yes, the NGK TR55's are already in (now, but not with the dyno) :thumbsup:Originally posted by Tomcat427
I looked at your chart. The lines on the graph scare me. I would get a new dyno with an a/f reading asap. After I installed the Long Tubes I switched to NGK TR55 plugs. They smoothed out my graph and the car was even stronger.
Congrats on being in the 300rwhp n/a group.:beer:
Now go run some 12's:thumbsup:
