When I had mine dyno'd, on a reputable dyno, everyone elses figures were what they expected from memory, and some we're actually down on power, from what they thought they'd make.MarkTurbo said:
So, that generalisation you've made isn't reality, in my case.
Mine made 318 bhp (249 bhp at the wheels) and 293 lb's/ft of torque at 1.1 bar (1.15 Kg's/mm) of boost.
The only mods I have, engine wise, are a 3" elbow, into 3" downpipe, into 2.5" system, from the flexi back. A Blitz SUS air filter kit and as mentioned, peak boost set to 1.15 Kg's/mm. I have done a few bits to improve the intake path though.
That's still with the stock TMIC and T28 turbo. If you do a search for the last Surrey Rolling Road day, you'll see the graphs.
So again, with the mods coffey has, specifically the FMIC, 1.2 bar of peak boost and the remapped ecu, he should be achieving better figures !
I do agree with Andy above though, and figures never tell the whole story and, don't really mean much on the road.
And I'll add that I only went on the dyno, to see how my AFR's were as, i'd done these modifications but, not had them checked in the past. It turned out that I was running lean, or so the print out showed.....

it is fueling perfectly and the guy doing it said it is perfect wich was great to hear
