IMO it's not fair for someone that is bone stock. But if you modify intakes (ie, after market cold box intakes, turbos, etc.) or exhaust system that will changes you to a modified class.
SCCA rules about being able to stay in STOCK:
13.9 Electrical System
a) The make of spark plugs, points, ignition coil and high tension wires is unrestricted including spark plug wires having an in-line capacitor .
b) On cars made prior to January 1, 1968, any ignition system using a standard distributor without modification may be used.
c) Ignition settings may not be adjusted outside factory specifications.
d) No changes are permitted to electronic engine management systems or their programming.
Looks to me like chipping is in violation of 13.9.d :cry:
