12th car veering on power

[beale]

Had a CRC Carpet Knife V3 for a while but only ever ran it during breaks before finals as normally run mini, TC a few of they drivers got a heat together of GT12s so thought stick a shell on and join them to make the numbers up.

Problem was as soon as you hit throttle from stop or slow corner it veers violently to the left, started to get used to it and the car is fast obviously should be faster than GT12 as it is a pan car but was such a handful was just hanging on, any ideas?

It is set up close to Mark Reinhard of 2006 but not sure what his oils were, diff tightness etc.
