thanks

 

im not sure but the same happened when i added a corksport catback......my solution..... APexi SafcII

 

Thats what I was gonna say was get a SafcII they will help alot, considering the n/a's run rich from the factory, what made you come to this conclusion?

 

Welcome to the club Fuel controller like said will help

 

where can i get one? and r they easy to install?

 

You can also start by fixing what's broken. Do a full tuneup and replace the coolant temp and air temp sensor. Adjust your TPS. Get your injectors cleaned.

By the way, how do you know it's rich?

 

exactly, do you have a wideband in there? i'd start with what aaroncake said. how is your ignition, compression, etc?
