Hello, I just wanted to let everyone know that last weekend Eric did my cam weld and tuneup. My engine is definetly cleaner, more efficient, faster,etc. It even shows it in the sound of my wicked flowmaster 40s. Sounds even better. I recommend anybody that could make it to the Chicago area to look him up. He was cool as **** and did a great job, with great documention to prove his work. THANKS ERIC<-------from CHRIS, another happy customer
