I have an 02 firebird formula so far ive put in a k&n intake, 85mm mass airflow sensor, 85mm throttlebody, and a 85mm inlet intake manifold.

The manifolds going in today and I was wondering would all this create a lean condition or should i just upgrade the injectors anyways to even out the increased air flow?

Suggestions very much appreciated

 

I would just keep your factory injectors. The factory 28lbers should be more than fine with the mods you have listed.

 

Awesome i'll post back if i have any problems thanks

 

No need to upgrade with that setup, stock will work fine.

 

Just to add to the above another thing to consider is that going with larger injectors are also going to require a tune.

 

Stock injectors are more than enough

 

whatt everyone else said as far as the injectors are concerned. Now on a different note, ever thought about going back to a paper filter? I know it seems backwards but ive gotten alot of mixed thoughts on how good or bad a K&N really is. From my experience (granted everyone is different..maybe i just over oiled it) the oil from the filter actually hurt my car seeing as it got all over the screen of my maf sensor. just a thought.
