Is anyone with the greddy kit on a Si having any problems with check engine codes?

 

I have one on my EX and had CEL issues (cyl #3 misfire) when boosting over 8psi...

 

What are the CEL codes that you are getting?

 

Can't you get a MAP Bypass valve?

 

13,14,71,72,73,74 Ive gone over the install and its perfect I,ve done 5 or 6 or so kits. Everything points to bad ecu but I was just courious?

 

Are you using the "blue box" GReddy provides?

 

of course. Install on it has been checked. I havent called greddy yet and I also have a local Honda Dealer that is very help full. I was woundering if anyone else was having the same symptoms. ? Any Ideas. The first problem I was having was code 14 IAC. I replaced it but the problems still are present. Runnig Factory plugs gapped down and they seem fine.
