Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit.

If you are finding that the valve is dumping more than required, or if you are losing boost pressure it is normally an indication that a stronger spring is required. Alternatively, if the valve is failing to dump it may be necessary to install a weaker spring.

Please note that fitting a stronger spring into a valve will not increase boost pressure, unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is too strong, may cause damage to the turbocharger.

Please also note that the red coded springs should not be installed in the DVR or DV007 diaphragm valves. 

Valve Spring color coding: 
Green - 5-15 PSI
Yellow - 15-23 PSI
Blue - 23-30 PSI
Red - 30 + PSI

Definitely Worth It
Quick and easy process. Coffee maker died and I had the insurance. Refunded and only ended up paying the price of insurance. Would do it again!

Claim was easy, speedy, and Amazon gift card was applied almost immediately.
I had to make a claim for a Ninja blender that was emitting an odor of burning or melting wires. I called a service representative thinking I might encounter a problem and was surprised. The agent was helpful and made the entire process so easy I applaud her! The Amazon gift card was posted to my account almost immediately after UPS picked the product up. I have decided that for products with a large number of parts and electronics that can fail I will purchase Asurion protection.

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue. My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty. And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan". They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.

GIFT CARD AS REPLACEMENT, NO CHOICE OF CHECK OR REPLACEMENT. GOOD COMPANY
PROS: * A decent company, responsive and fair. * Allows you to buy items from anywhere you want, and buy the warranty at Amazon. * Provides better coverage than other warranties, and covers more, including breakage! CON: They don't send you a check in order to buy wherever you want, send a replacement, or give you a choice. Instead, they send you an Amazon Gift Card. That's OK if you're a big Amazon shopper, but sometimes, you can get a better price elsewhere.

Asurion has been outstanding. Their customer service is quick, reliable, and efficient.
Every time I’ve had a problem, Asurion has been outstanding. Their customer service is quick, reliable, and efficient, and they handle claims with minimal hassle. It’s reassuring to know they actually follow through and resolve issues promptly.
