:iamwithstupid:Another upgrade I need to try.
Thats what I would think... To much $$$ for no HP gain.Rumours from Vette and GTO guys abound that unless you are making quite a chunk of power, they are no help...
OTOH, I've never seen a Dyno sheet to prove this.
I know two guys that bought them and would love to see 2-3 ponies. One SS truck ran the exact track times with stock ones and the MSD. The other truck owner says he can't tell a difference but he just gonig by the seat of his pants....no data. Don't wast your money. Paint your stock ones red for low $$$True dumping about $600 on shit that would only give me about 2-3 ponies is a waste of $$$$$$$$$
