Agree with this man most people map to 1 bar 220-240 bhp some run 1.2 bar which is around prob 250bhp and other have ran the full 1.4 bar at like 260+ bhp all depends on how much u trust your engine and how far u willing to push it really people will give u mix reviews yes some engines have gone pop at like 240+ bhp but then again I know engines that av gone pop n still running a ct9 it's like playing on the lottery IMO when I start modding and with the age of the cars it becomes a bit of a game of chance anyway
