After really struggling to decide whether to run the G or not today, I decided to risk all and stick it on.
Really glad I did as it pulled 161.3 BHP and 160.9 ft/lb of torque on the best run!!
I'm really pleased with that - was expecting 140ish as it has blowing exhaust, what appears to be a knackered blue temp sender and dodgy CO pot (which didn't change the a/f reading when wound either way.)
Got quite a nice line as well so all good.
The RR is accurate as well as my mate's Cupra R (180bhp standard) ran 188bhp with cat-back, filter and n75j valve - which is pretty much bang on to what it should be.
