I purchased a tune from 5 Star Tuning to update the truck. In discussions track side with another V10 owner, he was quite pleased with how a tune, headers, and exhaust had improved his truck. From online forums I read how the tune was the most significant upgrade of the three items and, regarding 5 Star tuning, everyone complimented them on their tune, service, and ongoing support. With a limited budget, I passed on the exhaust upgrades and ordered the 5 Star Tuning system.

Shipping was quick and no issues. Detailed instructions were included, as well as an SCT X4 Power Flash that was updated with the latest SCT software as well as the tune for my RV. RV’s typically get one 5 Star tune, whereas a pickup truck you would have more choices (economy, towing, performance, etc.). With an RV it is already a tow tune, performance is not usually a focal point, and economy – well, this is an RV. I let 5 Star Tuning know that apart from a K&N filter that my RV was stock. The tune is setup for your specific truck and the modifications that you have put in place. Installing the tune was simple and takes very little time. Plug into the OBDII port and follow the instructions. With that done I took the RV on a four and a half hour test drive to Watkins Glen International Raceway and back for a ChumpCar weekend. The van was flawless. It was almost ready for our trip out west. Phase 1 complete.

Basic maintenance was a must. Oil and filter change was completed with Amsoil Signature Series 5W-30 motor oil and an Amsoil EA oil filter – both rated for 25,000 miles so well beyond the limits of this trip. While changing oil on an RV is a snap due to the high ground clearance (no jack required), I had no interest in having to change oil part way. For about four years now I have used Amsoil Signature Series in all of my street vehicles (well, my Mazda RX-8 still gets dino oil). I stowed a partial gallon of oil just for safety sake – and sold it on the return trip to a traveller in a VW Vanagon whose diesel engine was alerting him to dangerously low oil levels. He checked the Internet to confirm it would work in his little diesel and then, five dollars later, headed off on his journey. I hope he made it!

The lifetime K&N filter was easy to service and I had the K&N cleaning/oiling kit with me so that I could do another service at the half-way point if needed. The transmission fluid has been changed and updated with Amsoil ATF – 18 quarts of it. The differential has been drained and Amsoil Severe Gear 75 150 has been installed. I just happened to have some on the shelf, as I switched from 75 150 to Severe Gear 250 in my Nissan – outlined in Search for Traction.
