any ideas? I really don't want to take the lts off but I would be ok swapping out the cats, I just don't want to blow them out like I did with the ceramic ones from carsound the first time. 2 years and they were gone.

So the 15mph test is what's really killing you. Did you get the car good and hot before you took it in for the test? You need to drive the **** out of it before you take it in, and hopefully you don't have a long wait before they get it on the rollers. Did you change the oil recently? Hc in the oil can hurt your test results. How close are your cats to your headers? How old are they? I don't know how much the G2P stuff works, but you could try it.

wow that didn't work out as well as I thought...
basically the test was 15mph and 25 mph...at 15 it 83 with a max of 51 for HC, c0 hit .47 with a max of .48, n0 hit 800 with a max of 419. at 25mph it hit 41 with a max of 35 for HC, c0 with .24 with a max of .46 and n0 at 316 with a max 706.

I did drive the car around for a while before going in, and they drove it right in. plus they never shut it off. just recently changed the oil. and I have the cats in the spot where kooks headers put them....came aready installed on the y pipe

What are the mods on your car? Are you tuned? Alot of times it has more to do with the tune than the cats.

hmmm yeah as mentioned above see about a tune CMS does great work I know several people who swear by ryne and those guys. could be too much fuel in the mix, or something isn't tuned 100%.
