^^^ some non-CP cars are ok at ~23psi+ you just need to log and check your AFR and trims etc, 50/50 chance. Mines ok by I use meth/water now to give extra head room so I am not relying on it.
Easy to adjust boost to suit cars max (all cars are different) a genaric tune doesn't give you this oportunity but a combo of JB4+BCM and a backend flash is best of all worlds...
