GDS CH-02

CH-02 good product . My turbo is more responsive.

Easy Peasy

The disaster prevention kit was easy to order and shipped fast. I spoke with a mechanic at Gillett Diesel for a couple install tips. Install was easy. Hopefully my CP4 will never blow. But, now I'm covered if it does. Will order again for other parts.

Pricey, but beats the cost of spending thousands more from a faulty CP4. Quality kit.

Finally a turbo that lasts

After replacing 2 turbo's from the dealer I had enough and looked else where. Luckily I heard about Gillett Diesel through word of mouth. Called them up and they explained exactly what was going on. Bit the bullet and purchased this new genuine Garrett from them, I fill confident going out again knowing I have their support and especially with the 2 year warranty the turbo comes with. Highly recommended.

Before installing this turbo on my 2018 6.7L Cummins I had a lot of turbo lag but now it spools faster and I have more power
