2011 ram 3500

Love this immediatel pedal response. Trucks is running really well. Took a short trip to Indiana this past weekend (8-2-24. Averaged 16.7 mpg at 80 mph. That means. Lot to me. I still haven’t hooked my camper to it yet, but I will soon. Hoping that tells me what I need the pulling power is needed there.

I’ve had it installed almost two weeks. I notice a definite improvement in performance, no more pedal lag or downshifting on hills (where we live there are hills everywhere. I know my mileage has improved but I haven’t done any hand calculations, but I’m thinking about a 25-30% increase! I haven’t towed my 12,000 lb. trailer yet, that will have to wait as it’s going into winter-storage before we get snow. So far I’m very happy, it’s a totally different truck!

We pull a 21k fifth wheel with one ram and a 10k fifth wheel with the other 3500. all stock except the stealth tuner and cold air intake. and the company is at the top of the page for help with your tuner and ordering is quick and easy along with shipping 10 across the board. thanks for a great product.
