Got stage one remap last weekend at AMD with a pipercross airfilter. Came up as 223Hp @ 3148Rpm as standard, now at 246Hp @ 4298Rpm although I had mixed 95 & 99 petrol in. Apparently AMD did some tests on petrol and said you can expect upto 20Hp more from 99

so I'm going to try and not mix and go for 97/99 where I can find it (usually tesco)...it was only mixed cause I went to Morrisons before and they didn't have any premium fuel

It's all very smooth through the range but when you floor it the difference it's made is very very noticable, from 2000Rpm my head flips back and it's almost warp speed.......and from the avg consumption figures I get 7mph more now

ALL good!
I'd highly recommend AMD (at Lakeside, Essex)
