I have an 08 with an ECS kit unrestricted with a single meth nozzle. The car started to break up above 5k in 3rd and 4th. I an sure it is in 1st and 2nd, but I can't tell since it just spins. I changed the plugs and put on a new belt. I don't have a way to log, fuel pressure looks good, A/F is around 11.2. Any ideas on the cause?

I was going to try wires next. Car has 66,000 miles approx. 15,000 supercharged. I gapped the plugs at .034. It made 719 RWHP on Vegence Racings Dyno.

You need to log whats going on before you damage something. Stay out of boost until you log it and figure it out.

I gap my plugs at .028. Probably a good Idea to replace the wires with that mileage. Check the old wires with an ohm meter to see if you have bad one. Always check the new ones before you put them on too.

As already stated, I would start with the wires. GLWI
