Buying a JLT Intake - need help?

Most tuners prefer PMAS signal, but all the good guys can easily make JLT perform.
JLT has been proven for a while.

My tuner said the same thing. Both are easy to tune and not a problem with either.

I did not buy the screen diffuser, should I ?

Havent installed my Intake or Throttle body yet, waiting on weather to get back to normal then install and drive to my tuner for a retune.

As mentioned, I had zero issues without the JLT screen diffuser on the JLT 123/148. No surging & steady idle. I installed it with the 148 one afternoon drove around and found no difference. I'm sure it's up to your tuner.
