go for it, then after you beat him ask him where that 30hp from the chip went to
i've seen both ends of teh sprectrum, i beat a supercharged 97cobra when mine was an auto running low 14s (REALLY bad driver) and a co-worker has a 96 BONE stock (even tires) ran a 13.6 on a crappy track
the driver is EVERYTHING in a manual car, i think you can take him, good luck
