Factory diverter valves are commonly known to leak or fail, especially with age or higher boost levels. A GFB TMS will hold as much boost as you can throw at it, 24/7 - No frequent re-builds or replacement required.Features
BETTER RESPONSE - Through reduced turbo lag - The GFB TMS is designed specifically to minimize lag - tests show that it can return the engine to peak boost up to 30% faster than a factory diverter when shifting gears, while delivering up to 40% more transitional boost (see GFB brochure)
BETTER DRIVEABILITY - Smoother than stock. Factory diverters tend to operate fully open or fully shut. This can cause annoying surging at freeway speeds, requiring constant throttle corrections to hold steady speed. The GFB TMS completely eliminates this problem, making the car smoother to drive.
GET THE SOUND - OR NOT - It's your choice! Want noise? GFB patented Respons succeeds where others have failed! By adjusting the venting ratio of atmosphere/recirc, you CAN acheive a sound WITHOUT throwing a CEL, running rich, stalling using more fuel or causing other problems commonly associated with atmo-venting valves.

Revised review
Size: 20 Inch by 26 Inch
I have ordered many of these pillows and loved them! Nice and squishy but didn’t flatten like down pillows. I needed a bunch for Airbnb but they are very pricey. Was reading the reviews and several said that the pillows had changed. I thought, how much could they have changed? So I went ahead with purchase. I felt like I may as well have gone to Walmart and bought a cheap foam pillow.
Update: finally tried the pillow myself. Although there is a definite difference, it is very soft and fluffy. Changed my rating from 2 to 4 stars.

Good quality, inconsistent shipping.
Size: 26 Inch by 26 Inch
Very good quality & fair pricing. Deliveries were challenging as you can order a maximum of 3 pillows per order. I had to cancel a back order & reorder. Not a big deal but required additional unnecessary follow up on my part.
