Hey guys, i've been looking for a while and haven't had any luck. I am trying to find a before/after dyno for a Cobb off the shelf stage 1 tune, from an actual member here, not directly from Cobb. Ideally I am more interested in the AFRs than the actual numbers, but anything will help. Thanks

 

I rane my 15 Evo X MR with the OTS stage 1 map and the AFRs weren't bad but I had too much knock sum.. from 1 to 8 increasing with RPM at WOT.

Cobb wad extremely helpful, looked at my data logs and told me that I needed a protune, that amount of knock wasn't normal. They also mentioned that it could be bad plugs.. you should data log and check your knock sum.
