I saw where there were a few that were going to or are using the JB4 on the PowerBoost. Any impressions/issues/numbers?

 

I personally contacted JB4, and they say it works, and if it doesn't, they will give a full refund.

My issue, I don't have the a way of verifying HP. If all that great, I know the companies & people out here have more than enough $$$$ to buy and test. My personal feeling it does little if anything, why no one saying boo. On another F150 site, a user said he purchased, but would not say if worked or not. SO I'm going to presume, no testers, no one saying anything, stay away, until someone who has a great reputation test is. One of the online stores I purchase Ford specific products no longer carries JB4 as of last month, so something must have happened.

It maybe great for other vehicles, but I do not think it will help the PB. I would have purchased it, but just not worth the hassle install, return and let down.

Just an opinion from old school guy....
