I have 99 GT with a Vortech S Trim Charger running 6psi. The car only has 58k miles and has been sitting for some time now. Might have put 200 miles on it in 8 months. It's time for a tune and I have been thinking it's time to upgrade to #39 cobra injectors and changing the pully to run 8psi. The car has 3" Pro Chamber H-Pipe and 3" Flowmasters. Is it worth the time, $ and strain on my stock motor?
