I got an email with a 20% off coupon (code: F150DEALS) for f150forum members on Flowmaster products. They offer a boost module that they say increases HP and torque. It costs $191 after coupon. Anybody have it or thoughts on this upgrade? Also considering their cold air intake.

 

The reviews for this snake oil device are pretty crappy on amazon, summit, etc. I wouldnt use it if it were me.

 

I would just go with a tune since the flowmaster boost module will reprogram your truck and show it was tuned anyways. Might as well go all out and get a tune.
