I'm sorry, but I have to disagree with some of you guys
1 - The 16v is twice as expensive to tune as an 8v because of the 2 extra cams and 8 extra valves
2 - The vernier cam pulleys WILL give a 10 bhp outcome even if the head isnt that much skimmed - given that they run on higher lift cams, and it's very much possible to get 135bhp with wrong ignition timing.... I got 155 bhp with ignition timing miles off
2008 pdf shows my STOCK 16v engine with a rear exhaust box only, which made about 140 corrected engine power and about 161Nm torques.
2009 pdf shows my then MODIFIED 16V engine (pistons/cams and ECU at the time) with MILES OFF the correct ignition timing. That measuring was in wheel power, but the guy at the dyno told me that those figures were +15% for the engine power, which meant that it was about 147bhp at the time.
Now, with a corrected mapping I got up to 165 bhp without fitting the cam pulleys yet, but it would tick so we lowered it down to 155 till I drop the engine down and fit those pulleys (at some point in my life
The Tuner is CONFIDENT by the readings and the mapping, that with the cam pulleys installed, I can easily go up to 180bhp if not more.
