Going from jlt 123 to dd149

[MTSWAP"D]

I had a jlt 123 went and got the dd149 do i need to retune it since the 149 will allow more airflow?

Yeah thats a huge jump in MAF size lol. Any time you change the MAF housing you need to have your tuner adjust your MAF curve. What T/B are you running? Just curious.

There is a new MAF function table you’re going to need to run that intake. Shoot me a pm and I can send you the correct table.

Did you need to go to the 149? I’d think you would be fine on the 123 with a twin. You should upgrade to a big monoblade TB to make the most of the intake upgrade.

I can't imagine much power will be gained going to the 149, especially with only using the twin 67mm T/B, but I could be wrong.
