I'm not saying I don't believe you, but how do I know you are correct about the spark plugs verse another tuner? I'm not as technical in this area, so I didn't completely understand the reason. Something about the way they work and as you increase the horsepower they tend to glow too much from being hot. Something like that. And in his experience he has seen the end fall off. It has another name. I guess the stock plugs work completely different than the TR55. They were built for fuel economy and longevity.
Also, my mistake about the lack of front O2 sensors. I thought I read that somewhere and I couldn't see them when I was on the ground under the car. I used my camera and then I saw them.
I spoke with the shop and he is pretty sure it is just a bad connection with the front O2's. He has seen issues with the extenders that are provided with the cats. I should be bringing it in on Monday and once it is fixed he just needs to remap the fuel trims, or whatever it is called.
This shop does have a very good reputation and has built some record breaking cars. Here is just some of the cars they did.
