View Full Version : HP gain with corsa on stock V

05-19-11, 12:42 AM
I installed a Corsa sport on my stock V and was wondering if anyone has done a before and after dyno pull, stock vs Corsa. Corsa told me I would gain 10 HP or so but it did not sound convincing. I wonder if I have acually lost HP. I will be putting a cai and tune in the future. Any help would be helpful.
