Well this was my old ecu, It never adjusted boost naturally and I always had an electronic boost controller it only ever adjusted it naturally on my black 850R (no idea why)
Everyone who went in mine can vouch how well it pulled with the 1/4 mile times or just a spin round the block the only reason I sold it was because the mods are starting to out grow the map and I didn't want to keep running my engine lean.
I wouldn't want you to feel like you have been ripped off by all means if your not happy with it I will happily refund you. But some of them adjust them normally and some do it on there own I have had it in all of my 850's (8 to be precise) If you have any questions send me a Pm or give me a call
