I just got back from Speed Inc. yesterday.(www.ls1speed.com) I had JBA headers installed and a dyno tune. I also have the Lingenfelter intake kit. I'm happy with the service I received and with my results.
I noticed quite a difference while driving home. The additional power IS noticeable. And it sounds great.
Also, on the way home I bought some shades for my plates. I saw these on a GTO at the Speed shop and had to have them.
The last two pics are before I added the shades. Click on the before and after pics together and compare them.
Is that an improvement or what!
That last upload is my dyno run results. I'm right at 360 HP & torque. I'm guessing that before I had this all done I was around 335 or 340.
