> 30% lighter wallet is all you are getting, ask people who have “dinan” tuning on their e39’s, it’s just not possible to get that much power. You wont even get 10% let alone 30…

Soo you think Autohaus’s 335 was a fake? He dyno’d it stock and with an f1 tune, exhaust and intake and got a 73whp gain… exhaust might have been good for 4-6hp and intake another 3-4, wherd the rest of the gains come from?
