so i had been contemplating getting the fabspeed supercup turbo back exhaust system w/ sport cat. on their website it states it will result in a gain of 10whp and 13ft-lbs. i also saw on their site they are offering a tuning option ($1,600 and you must send them your ECU) which claims to have an increase of 60whp/80ft-lbs for the 2.0 and 55whp/80ft-lbs for the 2.5. so the pair states a total increase of 70whp/93ft-lbs for the 2.0 and 65whp/93ft-lbs for the 2.5.
then i got this link in an email today.
it states the dyno shows 4whp/13ft-lbs increase for the exhaust and then 23whp/60ft-lbs with the tune, all on a 2.0. here is where i am confused. how can they go from advertised 70whp/93ft-lbs down to to 27whp/73ft-lbs on a dyno (assuming the tune added it's numbers to what the exhaust had done already, because if not the increase gets even smaller)? that's a pretty significant difference between advertised increases and real world application on a dyno (62% and 13% less respectively, 68% and 36% if the "tune"dyno numbers encompass both tune and exhaust). am i missing something?
