Supercharger install is worth every.single.penny. There's really not a better upgrade that I can think of. If you had trouble with a CAI install, then a supercharger install is far beyond your skillset and you should not do it. Hire a shop. I was considering doing my own, but with a Roushcharger to get the warranty it pretty much has to be installed by the dealer. It also gets tuned which takes at least 3 days while the dealer sends the ECU back to Roush for programming, so expect 3 days minimum of downtime. If its a busy shop it could be longer. They could pull the ECU, send it off, get part of the way done, start doing other jobs...mine overall took 5 days. But maaaaannnn....it was completely and totally worth it. Do it. Do it now.

When I had my 07' Gt, I drove it out to Brenspeed and had them install it. Worth every penny as there was no way in hell I was going to attempt it. Hats off to those that have done it. Took them ten hours, and well worth the $800.
