Dealer/ warrenty dilemma

[XR8GRL]

I have an AUII XR8 Ute purchased about 2 years ago. I purchased the car which was fitted with 250kw Herrod package ( cam, exhaust, chip). The car has had the chip replaced 2 times, leads, plugs 2 times and cats. All this was due to faulty chips.

Now the car still has a problem with this chip, even though it has been sent back to ChipTorque. The car runs very rough, drinks fuel like a twin turbo big block and the dealer will do nothing about it now even though the car is covered by an extended warrenty.

The dealer (service guy) said that because it is a modified vehicle, that the warrenty does not cover it. Even though all the other problems have been covered by the warrenty, they sold the car as a Herrod modified car and yet they won't warrenty this now.

I have talked to Rob Herrod and he said that he would help out as much as he can, and I'm very thankful for him taking the time to do this for me but unfortunately the dealer won't do anything about it. The car is as bought, has not been modified in any way since I purchased it and has not done an excessive amount of k's, warrenty still valid.

Any opinions?
