neither is good actually, as they both bypass the built-in knock protection failsafe.

between the two, the lindsey is a little bit safer though.

if you want to bump boost and still be safe, the only two ways i am aware of are;
1) the wolfe3d engine management system from lindsey
2) the megasquirt engine management system (build it yourself)

both retain the stock knock sensor and utilize it to protect the motor properly.
