I bought a jlt intake, and when I installed it, I hooked it up right, and tuned with 93 octane, and when I started my car it shakes,??? It acts like it has no gas, it sort of blew, like whistled like a blow off valve. Idk anybody help please.

 

My first guess is that maybe there is a vaccum leak or a poor connection somewhere. Second guess is the tune. Did you tune it yourself? What tuner? Did you mess with anything else other than the octane and CAI tune?

 

+1 TRY REMOVING THE TUNE AND SEE IF ANYTHING HAPPENS. IF ITS NOT THAT THAN ITS YOU CAI.
