Power figure is very strange after 140km/h dead flat at 300kw for 35Km/h the power to 175. The power actual peaks above the 140kmh at 154 and 164. If it was at a fast enough ramp rate you could easily over speed car on limiter till then which can give that effect of dead flat power

That would be because he rang the ting up in third gear instead of forth. Dont belive me 4th gear is 1.00:1 ratio 3rd is 1.302:1 So multipy his claimed 140km/h x 1.302 = 183kph which is close enough to call BS

If it is a hub dyno like a dynapac then it would be a accurate account as long as you enter the correct diff and gear ratio figures. But the tuner is using a chassis Roller dyno which introduces many other factors the main being wheel spin, inertia and size of tyre/rim etc. Your tuner is using a mainline so there is no reason not to be able to show rpm as it can be picked up from either coil or injector unless he is either too lazy to hook up or there is a bit of smoke and mirror action going on. A log of also the boost/rpm would also show response What ramp rate was it run up on??

How is Km/h more accountable when your claiming spool speed in rpm. Wheel spin will root up Km/h.RPM/KMH ramp rate can change speed of spool slightly but engine rpm is directly proportional to engine/spool speed Unless your trying to dodge the printouts and running in 3rd. Rpm would be best to back up claims
