Re: Evolution chips remap on a 156 JTS?
Oh they do vary greatly. The best way is to go to a couple and take a mid point. Also be very wary. After reading other posts about mapping and vaious rolling road company's who specialise in alfas apparently and companys claiming power out puts or certain gains etc I decided to spend some of my own hard earned cash and see what its all about. I took "a car" to a rollers of which I know the owner and asked for a straight forward no messing run what ever the car does it does. I then got them to map it for me. so I got 2 power figues. I then got the map removed back to standard and the car made the same origional power.
So i went to one garage and had the same thing done again, but left the map on so i could get it copied and compared, I did this to 3 companys and to be honest the results startled me. "trusted" well known companies are not 100% what they seem. Also as I know a few of the tricks that can be done to alter power figures to suit I looked out for them. " of which 2 of them where at the fiddling game and amazingly the figure i plucked from the air as to what power i was hoping for, they came to within 2bhp. fancy that.
Do some research first and use various companys, its not cheap but it will highlight who is taking the P**s just to make you feel good. Oh and the quality of the work I wasnt to impressed with to be honest.
