Had my bluefin installed a week ago, when accelerating hard it seems to stutter slightly.

Cant determine if theres a fault somewhere or its the traction control getting grip.

No ecu light or traction light comes on so im after abit of info from you guys if poss.

Cheers.

Get your codes scanned

So even though the ecu light isnt on, i may still get fault codes when scanned?

Yes.
