i fitted 1 on my agu and it was fine you only have 1 lamba senor at the front so no need to worry about it,if you had 1 at the back then thats the 1 that will send it crazy.

ecu was fine aswell m8.

De-cat won't ruin the car

Lack of MOT will though

More top end bhp, but less torque low to mid-range. ;)
