Speed Tuning USA chips for W210 E55?
also they have software for new W211 for $350 and the gains seem very nice as well.
any input would be appreciated. thanks
I also asked if they had an actual dyno printout of the chip performance on a (W210) E55 AMG, all they kept referring me to was their website and the dyno chart thereon (which I do not really trust).
Just my opinion. I hope that I did not offend anybody.
If somebody does have their chip, please let us know the results.
