well, i installed the aem brute force, looks/ fits good, sounds good. but i noticed when the motor is warming up around 170f or so when i accelerate whether its part or full throttle it seems to "cough" almost like turbo bark as others have described, and lose power for an instant. I never noticed it before with stock airbox. it will do this once and thats all. weird. is it too much air?? i ordered the edge j/a today and should be here tomorrow and the mbrp 4" will be ordered next week. so what do you think... i'm all ears. 1000 miles on truck.
