I got to thinking.... yeah, yeah, I know... anyway...

Best I recall relative to the EPS rules n' regulations that 1997 was the last year engines could be modified without right stout penalties. Sooo... is Hydrotec only modifiing those engines '97 and earlier or???? How are they getting around the EPA with mods?
