all maps will be on safe side on a rolling road eric as cannot load car as would do on the road...
but then u would like a safe map not too safe where u loose power, but not say making unsafe for an extra ten horses.
im lucky my mapper is 2 min from me with his own dyno, so when he aint tweaking his 106 he squeeze me in.lol
your going to hear good and bad things about everything in life so u will with mappers matey, so go with one who can give you value for money
He mapped it on the road after. When i say safe he had the fueling spot on 11.8 without it detting but brought it down to around 11.5s if i can remember thos figures correctly.
