People only seem to be interested in a tune that gives them a deal.I checked out the Westers site and they charge $500.You sell their product for $400 and you give a discount on a group buy.Why doesn't Westers reduce their price? Why can you sell the same product for less?
Vector don't have their own HHR for the same reason that K&N and AirAid don't have one - they all use privately owned vehicles as their test mules.You can't own every vehicle that you have to tune for.Good to know that you do.
I look for the best deal too, so I guess I can't fault others for doing the same.
