..lol viper >GTR with any other driver but this guy.. a tune on a gtr is good for about 40-80 hp. a tune on a viper..20.. maybe. LOL @ the "NOT A v10" comment. remember this is just a normal viper SRT10. it's not an ACR... had it been, would have been a much different race... and why are they always going up to 186mph (300kph) z06 is done at like 190(other race)..no wonder the gtr catches it it has TURBOS dur lol
