Renntech does Mercedes Benz SLR McLaren 722, again

Already having a 722hp engine upgrade kit for the Mercedes Benz SLR McLaren 722 in its shop, the American super-tuner eventually came with another, even more extreme, tuning program.

The new tuning package consisting of a reprogrammed ECU and a 'less restrictive' exhaust system, lets you squeeze extra 18hp of the SLR's 5.4-liter supercharged V8 engine increasing the total power output to respectable 740hp.

The kit may be ordered together with the new Renntech Signature 10-spoke, 3-piece performance wheels.
