But quick question.
You mentioned that COBB uses more boost (18+ psi compared to 14.5 psi JB4), with different maps/settings, can't you change how much boost you are getting?
Thanks again for your review! You have cleared up some of my confusion.  |
Both Cobb and JB4 have had developments since the review was done. Protuning is available for the Cobb and Jb4 now has isolated boost control for those who require.
There are fair few different Cobb maps available depending on your mod level and driving requirements. I'm switching to a JB4 and Cobb combination so the best of both worlds
Is there a Cobb protuner close to you? If so, I would buy the Cobb and then have a custom map done by a local tuner or a remote one like ProTuningFreaks.
