I ran a search, nothing came up. I'm sure you guys talked about this earlier in the year. Is this engine better to chip now that they have improved the hp by 20 more horses?

Default yes, new pistons I believe

possibly larger injectors, obviously a bit more boost, wonder if the timing is different

James?
Anand?

I don't know if this is true because on audiusa.com under the complete specs it lists when the motor has vvt. The 2001 doesn't specify that it has vvt like the other motors.
