I have b16 and i just installed an itr intake manifold and also changed my fuel rail with a gsr fuel rail because my FPR got in the way with the air temp sensor, anyway i drove my car and my air/fuel gauge was running a little lean and when i went into vtec and it began to bog, after this the air/fuel guage wasn't running lean anymore...is this normal after the install?

 

is it normal now

 

yeah
