This tuning stage was created for the biggest power increase without carrying any internal modifications.

On this we fit our intake manifold, our cams, standalone ecu, and we do recomend exhaust for better results. It can also be done with stock ecu but will not be able to deliver same performance level.

gains on this tune are around 30% on power and around 8% torque

avg power 5000-6500 increase is also around 30% more and from 5500 to 7000 40% gain in average power production, this tune still offers great drivability with a great engine note.

on graph presented values are at the wheels

value for a drive in drive out stage 4 is £2700* or £3200* with exhaust as well
