The test we did was a quickie favor at no charge so we didn't get a print out. I was more concerned on the car passing or failing rather than actual numbers this time around. We took it in " cold " to make it easier to fail if it was going to but it did pass. I asked the tech where we were in the pass fail range and he said the car was fine but " possibly " lower hence the " dirtier " comment on my part. If others think the actual numbers might be of importance rather than whether it fails or passes I will go back in the near future and give it a actual smog check with a print out. We do find it amusing that this is the first time this question has come up with all of the other products out there already that also affect smog readings but its al part of the fun and games on here . Thanks for the support

That means any nonstock aftermarket part that is installed on your engine must be EPA-approved and emissions legal (except on the exempt vehicles previously noted).

Also, it looks like there is more timing at ~180 than at the ~195-200 degree range...which means more power.
Don't look at the timing in the graph before it gets to 180. Look at the timing at 180 and at 195/200 since that is where the engine will run. It looks like if you can keep the temp at 180 you will have more timing....although it only looks like a few degrees.
That being said though, I go from experience...every vehicle (95 T-Bird, 01 GMC, 02 GMC)that I could put a cooler t-stat in, I did b/c it ran cooler and had a little more power.
