Bought a Stage 4. Put it on the car. Made a little power sounded good. Tried to get more power out of it called them about it. They told me to change intakes/Maf /Plugs / Tuners. Changed around some things... didnt make any more power.
Sold it and took a bath on it. Upgraded to a whipple never been happier. Customer service was about Par for the course i didnt get cussed at
I know when we put the Snakebite on my friends car it didn't put down the numbers we were hoping for so we called Stieg and he recommended that we remove the cats. We took all 4 out and it didn't pick up a single HP...lol. That was pretty disappointing but it happens. I think the biggest problem with ported blowers is how many people advertise HP #'s. If I was going to offer any recommendations to Stieg I would advise them not to advertise HP #'s so much. I know the blowers should put down 500hp+ but it's not going to be the same with every car.
