Stuboy2UK: I had an Angel remap on my 10V 156. No RR print out but absolutely no doubt the effect was jaw dropping. We also have a 159 20V. Side by side the 10V 156 stomps the 159 into the dirt. Any speed, any gear and our 156, an early one, left the factory with just 130bhp. Angel quoted 200bhp, I don't know if it made that and I know the 159 is a heavy beast but the way the 156 went and the way it leaves the 159 for dead it can't be far off. Side by side is my wife driving the 156 and me in the 159. The 156 had no modifications what so ever, nothing uprated and no Q2 - it did need a new clutch every 30 - 35k but we revelled in the torque and abused it. Nothing else broke.
We also have an AHM remap / DPF removed and EGR delete on the 159 to 238bhp. This was done after the 156 was sold so no side by side comparrison. I suspect that with low rev roll on the 156 would be quite a bit quicker but as the revs build the remapped 159 would catch up and maybe (maybe) go by. There are traffic lights at the bottom of the hill where I live and the 156 would hit the crest at just under 85 and the remapped 159 hits the crest at about 90. My 1200 Trophy hits the crest at 110 but I've already backed off the throttle by then - it's a blind crest!
In summary - the effect is jaw dropping. If you burn rubber and use the torque below 1800 rpm then you are risking your clutch in a 2.4 but other than that I don't think you need to worry. Certainly the only issue we had was the clutch in the 156 - nothing else has broken.
In hindsight I would fit a limited slip diff as the extra torque does cause torque steer and in the wet easily spins the wheels in second and, in tight bends even third.
Again summary - just do it, it is amazing.
