i personally have met Mike Huml numerous times.. he is a member of my DSM club.. he owns Slowboy Racing.. they sponsor our club..but his turbos are VERY good. I would not recommend a 20g unless you got a shitload of money because the supporting mods will be fucking expensive.. i see that you are a GSX.. maybe get a Big T-18 killer or Small16g? I mean fast spool + no wheel spin = fun
