If you aren't getting any CEL's, fueling is probably fine, if not optimal.

I was not getting any CEL after installing my set up. However, once i had it professionally tuned.... It showed my engine was starving approx 20% gas needed.

Lean fuel can result in many issues!

Rule of thumb when modifying engines...... Once you're done the installs..... Get it tuned!!
If you're planning on many add ons....tune once your build is complete.
Even a simple CBE needs tuning. If u also add CAI u Definitely need a tune
