Thread bump. Great thread guys!
Ive had -5s and GTSS, the -5s felt exhilarating whereas the GTSS IMO were boring. But like many have suggested, depends on your application.
I'm pulling off my GTRS snails at the moment...what fun that is working out of the engine bay.
Mine is far from a weekender which is sad but true.
GTSS setup made 325awkw @ 23psi
-5 setup made 340rwkw @ 19psi (I question this though as that number sounds a bit high, maybe a happy dyno?)
