Easy install/ Good results

Did exactly what it was supposed to. More passing power/ better response after the transmission shifts

Upgrade your Kia stinger with an easy to install blow off valve!

I ordered this part and it arrived in 2 days with free shipping. The box itself was packaged very nicely with bubble wrapped to protect the part. It took about 15 minutes to install and I’ve never had so many compliments on the sound, even my brother tries to zoom off in it lol. Going through punishment racing was actually cheaper than buying the hybrid gfb bov from throtle! I HIGHLY recommend this parts dealer.

Vibrant Flexible Interlock Wastegate Dump Hose

Exactly as describes!

High quality easy installation! Only con is bumper had to be cut a bit for it to fit.




I ordered the GFB diverter valve for my Veloster on a Friday.. got it that Sunday! Super fast! Awesome experience! Would definitely recommend! As for the part it as well is an awesome part as well. Sounds bad ass and does what it says!

Awesome product

Great quality would buy again!!

Great product got here really fast

Fit correctly

Fits but it leaks

Great Price & Quick Shipping

Glad to have found this GeForce-3 boost controller at such a low cost. This was pretty much the last piece needed for my single turbo 335is! Shipping was quick!

good fit, bolts right up

thought it would be to small of a piece but the oem hangars bent enough to make it fit nice and snug.

Great boost controller

This is a great boost controller, lots of features and easy to use. What made it even better was punishment racing, they ship quickly and have the lowest prices, thanks guy!!!! A+

Quick delivery

Have not had a chance to install it, but it was delivered quickly and in good shape.


Found it the cheapest on this site, haven’t had the time to install it, been waiting on a few more other upgrades as well.

Flawless Boost Controller

Received it 2 days after ordering. The user interface is easy to use. The range of control works great. Definitely improves spool time and boost bleed at the top end. Highly recommend


Got this because I changed my stock intercooler for a larger. Quality is AAA, packaging, engineering, quality of production!!! I am speechless. Did the job and increased my boost to the required psi! Great work guys, great products and fantastic tech support!

Excellent Part!

Fit perfectly on my 1992 Miata with a Manzo Header, and OBXR Single tip exhaust. Highly recommended!

Fit great!

Shipping was fast & packaged with care. Quality is nice & install was a breeze


Awesome intercooler.
