I don't know everything there is to know about calibrations and I certainly don't claim to. He was making claims and spouting information off that only made him dig a deeper hole. When I contacted him via PM I approached him very seriously and professionally. He just talked in circles and wouldn't go into any detail or even consider my offer to validate his product. If I can remember where I put the saved PM's I'll post them up..... It's good for a laugh.
Jims performance- great company with great products.
Wayne Hartwig- bad for your engine!
Hmmm, I was not aware of any of this. I'm glad this has come out. I won't be going to him when the time comes like I had planned.
