its not really an mtm big turbo s3 at all, if you read it it has an mtm re-mapp thats all so no better then say a revo'd or custom code s3 except he's put on a garret t28 turbo which is probably only an eliminator kit to getting 300bhp plus wont be running properly with that turbo either because it only has an mtm map that id guess is just generic, id rather by just a re mapped s3 in better condition
