Congrats on getting that running, driving and to the track. Tell your son to take a data log for every pass down the track and then he can look at the data logs on his laptop or desktop computer. The data log will show the RPM, air fuel ratio and things like that as he makes a pass. That way he can see how well it is tuned.

Are you controlling ignition timing with the Sniper? If not, you can buy the Hyperspark distributor and then you'll have full computer control of the timing.
