But yeah, Protomotive and Evolution MS make some bad ass Porsche's, and GMG is right up there too for domestic Porsche tuners.

If you like twin turbo Viper's check out Heffner, 2000+whp..

wtf bro heffner 2k+? where. it is not on their site. i thought that viper was the best out there.

ps: what is gmg tuner for porsche? never heard of them.
