I've just had a great day at a track day, fast as you can but NO racing, let onto the track 1 second apart, NO racing :ROFLMAO:
Anyway on the way home I notice a loss umph pulled hard from start up to 5000rpm ish then not the normal pull to 7000rpm.
It was pulling hard to the red line on the track, P.s it's got a few mods on it ecutek, air filter, inter cooler, cams and springs, exhaust,
free flow cat, I think that's it. I wouldn't think any of the mods could affect the loss of power, maybe the ecu but would it fail just like that?
On the way home everything felt okay at normal at road speeds, also the idle was fine, another thought you might ask, no there where no
signs of it over heating on the track, no I didn't do the dreaded gear of death. Any thoughts out there.:unsure:
Cheers and good night - talking to you from Australia
Lofty.
 
You have the ECU connect kit for data logging yes? That provides diagnostic capability to help diagnose in the first instance.
