| I posted a wanted add for cats on my na As far as my twin turbo here are the numbers of why I didnt pass 15mph test for NO (ppm) I was at 2423 and the allowed amount is 767 so I was way over at 25mph test NO (ppm) I was at 990 and allowed is 706 On the 15mph test HC (ppm) I was at 149 and max I could be at was 108 I have 555 injectors, single pop,dp,borla exhaust, built engine with 5k,jwt 500 cams, gt 28 turbos. Im going to take my high flow cats off and run my stock cats.. Im pretty sure my boost controller was set to no setting so it should have been running lower boost.. Anyones input would be great..this smog shit is making me want to make my car a track car.....
