Hello everyone... I am trying to figure out what is wrong with my FC. Over the past 2 months power has been on a slow decline... I pulled the plugs out today and the have a nice color to them...so I dont think its that... It just does not seem to pull like it used too... Replaced the cat about a year ago...so...its not a cloged system....

ANY IDEAS?!

 

Check the compression...always the number one thing recommended here...albeit I'm boosting on an engine I've never done it to...heh

 

It this a turbo car, that were talking about?

 

Non-turbo. Stock NA.
