When I first installed this unit, the performance was notably better, but the afr below 1500rpm was lean and produced off idle stumble, rough idle and codes. Spoke with the guys at Granatelli and they sent me the c-plus model. The performance after install was outstanding. From idle to 6000, the truck just kept pulling. I have owned this truck since new and for 60k miles have always had just a little jingle at idle at times. This is gone now, idled smooth, plenty of pulling power and one very happy customer.......thank you


Originally purchased 350115 C+ for my application. Had some issues with running too rich, but after contacting customer support they warranted the part with no questions asked. The 350115-C is the perfect combination for my 5.3 with cold air, throttle body spacer, tuner, and custom non highway use exhaust! Excellent product and great service. Thanks JR!
