I have a Whipple charger on my L05.  I'm pretty sure the additional air from
an increased air flow TB would not be a problem (except possibly the cfm
rating on my airfilter <g>).

Would just more air flow create a lean situation?

Do you think higher rated (over stock) injectors would also be necessary?

I'm new at this, so I'm assuming *recalibration* would be reprograming the
PROM for the changes to the hardware (?)

Thanks for your reply,

Bob
