You already got billet servo and shift kit in that trans yeah ?? Have you got an aftermarket trans cooler on it ? If it makes you feel any better that is the heart brake dyno if you went to any other dyno dynamics place around ie boost worx or willall you would be getting a reading of 20kw higher so around 290kw wich is good and what you would expect from that set up . E85 alone will see you up to 300 on that dyno and 310 315 on any one else's , don't need a high mount unless you want to go for one for looks , unless you intend to chase much bigger power figs later, I still run stock inlet and exhuast manis for the moment , good effort good to see more and more stags getting close to and getting into the 300
