Ok, let's talk about the car which is what really matters. Again, this starts with complaints. The air conditioning stopped working. Yes, things happen, and yes, it's hot in Southern California and you want AC. The issue as Weistec explained to me was that the steering wheel control module went out. This can happen to a stock car and has nothing to do with the turbo upgrade or anything Weistec modified. Things happen and it is something that is fixed by replacing the module and resetting the codes. Matt did not have AC or manual shift mode during the review.
Not a big deal and when he gets on it he quickly forgets about the inconvenience as he should. The power makes him giddy, again, as it should. Good, now we're enjoying ourselves. His butt dyno states it is making every bit of the advertised power.
Steve at Weistec then makes a cameo to go over all the components in the turbo upgrade. It's a completely bolt on upgrade system which is nice and gives it an OEM feel. A quick overview is made of the components and the other things Weistec does such as all their work at the forefront of the M156 AMG scene.
Steve goes on to further say the car puts down 715 wheel horsepower on 91 octane pump gas which is impressive considering California pump fuel quality is not. There's more in it on race gas of course. There are some great shots of the car doing burnouts and WOT throttle pulls.
My feelings on the review are mixed. Obviously the car is impressive as is the Weistec upgrade package. Matt's comments seem to come from someone not very educated in the M157 tuning scene or what Weistec has accomplished however. Look, yes, the AC and steering wheel transmission controls went out boo hoo. How in the world does that mean the Renntech tuned car worked better? It's not tuning related as he later finally states. Additionally, the Renntech car was their bolt on car not their M157 turbo upgrade car so hardly apples to apples anyway. I feel like a mountain was made out of a molehill.
Overall, the car is impressive as is the Weistec turbo upgrade package. This review? It focuses on the wrong things and starts off on the wrong foot. It doesn't do it justice.
