Yesterday i received my set of smoked headlights so i was so excited to put them on i ran outside and did...After i was done i wanted to check over a few things Guess what i found...in the back under the upper intake its A Trickflow street heat...there was a Vac cap off...How long it was off i have no idea...so i capped it and the idle went down so i adjusted that,and i took it for a ride and i have no idea if this was causing an issue but the PCV didnt blow out or the breather... car ran great,,the only thing i noticed was it would go a little richer quicker of course it would it doesnt have a Vac Leak now..idle is still perfect just like i said a little richer when getting on it..went into boost so it goes down to were it always did...I hope they didnt tune it that way or it blew off on me a few weeks ago...or something that is scary i have the car here today ran great..should i just keep an eye on it or what????? Also what are your AF reading while driving...car idles between 14.5-15.0 and driving it goes from 14.5 to 13.5-13.8 then when i hammer it goes down to in the 12's then in high boost 11's is this ok?

Id say youre alittle rich at cruise at 13.5 - 13.8 everywhere else is good though. You want it a little lean at cruise for fuel economy.

At cruise its anywhere from 14.0-15.0...if i start getting on it the af gauge will move down slightly to high 13's then when i mash it 12's-11's is that ok?..the gauge moves so fast tho....lol..at idle its between 14.7-15.0 all the time...sometimes high 15's

It sounds like your tuner did a pretty fantastic job with the af then. At cruise I'm running a little leaner than that around 15.7 to 16.2 and as soon as i start makin boost it's at 11.5 to 11.7 until I let off of it. Ideal af differs from car to car Ideally turbo cars like 11.2 to 11.7. But like I said, every setup likes something just a little different.

It won't change your tune a bit. It will prevent the oil from blowing out of everywhere it can though.
