Will everyone get off the batmo bandwagon already. What have they proven?? Or is this just another bullseye sales pitch?
I've talked to multiple VERY reputable turbo shops and they have dyno results showing no improvement with the bat. Even a loss at some points.
2 manufacturers actually told me they would rather not take my money for a billet wheel and instead sell me a cast so that I would come back when I was ready for my 400 series.
If you want me to chime in with more info I can.
Save your money stay cast on the 300 series charger.
As for you guys going from a Vgt to a non, take it from first hand experience, it does not spool like stock. Take 1300-1500 on a stock charger, and relate that to 1800-1900 and that's just boost not even fully lit.
