Im currently running a trick flow 75mm TB and Plenum
I've read that a 75mm TB/plenum combo or higher is too much air for a NA engine. Is that because the stock fuel injectors wouldn't be able to supply enough fuel to compensate? And if that is the case would upgrading your manifold and injectors to say 30 lbs or higher balance it out and produce more power?

 

have you tuned it to compensate for the increase of air?

 

Yeah I have thr SCT tuner. I was just wondering if upgrading my injectors would help if I decided to get like a 90 mm (hypothetically speaking)

 

You're not going to see much difference on a N/A engine. It's not necessary with just a t/b/plenum. Unless you have internal work such as heads/cams/intake I wouldn't worry about injectors at this point. The stock injectors should provide properly with a few simple bolt ons. If you haven't already, I would suggest doing exhaust work to let her exhale.

 

I've got a flowmaster catback and off road x pipe. Right now I'm trying to decide if I want long tube and a shorty x pipe or just get regular headers.

 

The shorty headers would cost a lot less but the long tubes with an o/r x would make that v8 obnoxiously loud.
