Thank you for the responses. I was also running 5v but is VIN locked so I went back to v4 and using v4 firmware and v4 maps to avoid the flashing CEL. What am I missing out with v4 instead of v5? I really just wanted higher boost. Probably not going to do meth or any other mods just looking for that extra jolt to bring a smile every now and then.

When I bought it, it had just been updated by Vishnu to the latest v5 firmware and maps, I am pretty sure they did the O2 sim update while they had it.

So far so good no codes thrown yet.
