Just curious whats your car in for? And hows your car running with the pully. Do u think that the ASP pully really makes your car faster than the Kleemann? i am only asking because i am finally serious about getting the pully soon.
thanks

Although the a/f ratio is a little high, it's not throwing any detonation codes. Most of the time while you are driving, the wastegate bleeds off uneeded boost so you're a/f ratio should be the same as before. When you go wide open throttle, the wastegate closes and you get full boost, this is when it gets lean. Lean by itself is not bad a long as your combustion chamber temps don't get too high and cause pre-ignition which it's not except at very high RPM's above 5,500, enough to pull back timing but not enough to throw a code for too much. I'll take it to the track again when the issue is resolved and I have time.
I'm working with the MB dealer to correct this but we ran into a little snag with the ECU and it needs to be fixed first, hopefully at then end of this week or early next week.

how does the kleemann pully have a lower A/F ratio.?

Crossfire Coupe
the new Jetta 1.8T auto. is amazingly quick on the low-end. Great acceleration for what it is, a 1.8 turbocharged 4 cylinder and automatic. It really doens't leave you begging for more power like the older 150hp generation of the 1.8T. The 2.3 C230 is a proven engine that is great at what it does, albeit a little improvement in the sound and dampening dept., but nonetheless a great engine. HOwever what pulls me away from the VW 1.8T would be the fwd setup. You really cant enjoy the full power the 1.8T 180 HP engine has to offer due to tire spin out no matter what. Whereas the Benz pushes you in a very linear fashion like a miniature rocket down the road. If VW would change the set up from FWD to RWD they'd have better performance figures and handling i think. Just my 2 cents of owning products of both makes. Example look at Honda with the S2000 can you imagine an S2000 FWD??????

Hasn't VW always had a FWD setup? Wouldn't you also get less wheelspin than a RWD since the weight of the engine should help with traction, or do wider tires in a staggered setup compensate for this? I wouldn't think it would be s perfect offset.

No, VW began with RWD roots (think Beetle and Karmann Ghia).
There are a million reasons why you get worse wheelspin with a FWD car, including the fact that the cetrifugal force of the engine actually rocks the torque up off the wheels, and weight transfer under acceleration is actually from the front to the back, taking weight off the front wheels.
Most importantly is that for any given tire, there is only so much coefficient of friction. If some of that friction/traction is being used up for acceleration grip, there is that much less for lateral (steering/handling) grip. A RWD car uses the front wheels for steering and the rear for driving, an FWD car uses the same two for both.
Finally, you can't "steer" the car with the gas pedal nearly as much with a FWD car. w/ the exception of rally cars (a completely different rule book), look at all serious forms of road racing: RWD.
