Here is a link to Weistec's website, argue with them about their claims, I would think if it made more power they would gladly advertise it, not too many tuners out there lowballing their hp claims, but plenty of them inflating them. This is why I am sometimes embarassed to be a BMW owner, some of you guys are stubborn, mis-informed and think your cars are unbeatable...did a lot of you guys own Mustangs in you early 20's lol?
The ACG car, Stage 2, did make 630whp, but maybe he had additional supplemental mods that others don't. My buddies Stage 2, Josh made 608whp STD, and I saw that an SL63, I think Stage 1+, made 603, but I'm not familiar with what additional mods may do, and how Weistec lists the power, as most know the 63 can pick up a lot with headers, etc. Either way, they've made more than the advertised power, which is good and not uncommon in every platform. From the many runs I've had with friends, C63's, BS, CLK, etc. they have always needed more power just to run even with me. It's ironic that my best # is "667" too, lol. Either way I admire both setups, and we've had a nice civil discussion here.
