Customer video review of Mechanical Boost Fooler

Good people and great products! Thanks Brian!

Was going over 22 psi causing my truck to go into limp mode now that I add the boot fooler my truck is able to do way more and no more defueling caused by limp mode. Worth the money!

Did exactly what it was supposed to

Plenty of hose for a clean installation. Double checked set point and was on. Exactly what I was looking for and so far preforming excellent. Brian keep up the awesome work you and your guys are doing.

Love it so far so good tunes are awesome

Great part

Works as it should. Wish there was a mounting bracket it kind of just sits in the engine bay. Also, would be great if there was instructions not for me it’s a pretty straightforward install but to someone less experienced or familiar with the engine.

Works as expected.

Worked great and super easy install

Products works great and got here on time

Haven’t put it to a full 5th wheel pull up the pass yet but so far no more CEL

Works

fixed my over boost problem immediately

1996 7.3 works great, plugged right it and ready to go

I had to do some minor adjustments to set it to 19 per in order to keep the code from popping for over boost but seems to be working like a charm now.

I love the HYDRA TUNER AND ITSBTUNES .AND THE BOOST FOOLER DID THE JOB HIGHLY HIGHLY RECOMMEND

Easy install and works as it should. Thanks jellibuilt for carrying such a wide selection of products!

Would have liked the black hose instead of the gray. Instructions would have been nice to. Where to mount? All in all. To pricey for it all

Fast shipping and Top quality products!

Bryan , has been a pleasure to work with since day one, bought six months ago purchased A hydra with custom tunes package, then a HUEI. And now a boost fooler.. every step my performance has increased. Trans shifting better from the HUEI Then I started experiencing over boost code 29 plus pSI. From full throttle. To decel throttle would lean out and get choppy. Again I emailed Bryan He suggested Boost fooler. Installed I was able to get more in in then experienced over boost again plus 29 but I instantly had less lean choppy ( under fuel) Emailed he immediately responded instructed turn 1/2 turn clock wise…. Think I went little too far. Cause boost numbers dropped to 14. Psi. Soon back turning 1/8. Thank you Jeli

Easy install works great! Brian is awesome for any support
