I have a 2000 camaro ls1 w/street heat 2 cam,241 ported heads, ls6 intake, lt headers, UDP, true duels, 100 shot nitrous. I had a shop install my kit but they never checked my plugs, they tunned with plugs that were in it. I checked them and had tr5's in them well I thought bet to that in a sec. I asked my tunner what plug I should use and he said br7's so I bought and installed, I asked if I needed a retune and he said no it would be fine. I ran them for a week and got a SES light, when I changed them I had two diffrenet kind of plugs had tr5's on driver side of car and tr6's on passenger side. What kind of plug should I use and do I need a retune, thanks in advance.

Definitely use the BR7's and no you do not need a retune
