There is a noticable difference with the engine mods. Both cars have the C&L kits with Predator 91 Octane tunes. At the 1/8th mile drags (best we have around here) The convertible was .6 second and 5 mph faster than stock tune. I haven't got a good read on the coupe because it's a stick and the tires love to go up in smoke.
