Test N Tune

Once the truck was up and run­ning, the camshaft had been bro­ken in and ev­ery­thing was checked and re-checked, it was time for a test drive. Af­ter leav­ing the shop, it didn’t take long for Canale to re­al­ize the trans­mis­sion was stuck in 3rd gear, so back to the shop it went. Af­ter some di­ag­nos­tics they dis­cov­ered the TCM flash hadn’t been com­pleted, so Wil­son Pat­ter­son Diesel emailed over a file to try out. Thank­fully, this re­solved the is­sues and now the truck was driv­ing ex­cep­tion­ally well. To dial in that big fuel-andair combo, Cal­i­brated Power So­lu­tions put to­gether some en­gine tun­ing with EFI Live. It keeps power and smoke out­put low for daily driv­ing needs, but there are of course a few big tunes on tap via the CSP5 switch.

The truck sits on a Carli Sus­pen­sions lift kit with Fox 2.0 shocks all the way around. The big Amer­i­can Force 22x12 Evo 8 wheels are wrapped with 35-inch Toyo M/T tires. Calvert Rac­ing Cal­trac bars help plant the horsepower on the street, while Vi­air on-board airbags and a B&W goose­neck hitch still al­low Canale to tow should he need to. Cos­met­i­cally, the truck was kept classy and sim­ple with a paint-matched front grille and bumper, Bushwacker fender flares and blacked-out Anzo head­lights to fin­ish off the front end. The rear bumper is a paint-matched Fu­sion Bumper with Rigid back-up lights in­stalled. In the cab, things are kept ba­sic with noth­ing more than an Alpine stereo head unit, some LED light­ing and fac­to­ry­matched Au­tome­ter boost, py­rom­e­ter, trans temp and fuel pres­sure gauges on the pil­lar.

At the time of our photo shoot the truck had only been run­ning a few weeks, so there were still some tun­ing ad­just­ments to be

 The freshly built 6.7L Cum­mins should han­dle 1,500 hp thanks to bil­let con­nect­ing rods, a Go­rilla gir­dle, main studs, a 220/230 camshaft, fire-ringed, ported and pol­ished cylin­der heads, and all the other sup­port­ing mods. The Borg­warner 76mm SX-E is mounted on a waste­gated T6 Steed Speed man­i­fold and that cus­tom-machined Al­li­ga­tor Per­for­mance bil­let valve cover tops it all off.

 Look­ing up un­der­neath, you’ll no­tice the orig­i­nal 68RFE trans­mis­sion has been swapped out for the stronger 48RE ver­sion used in the ear­lier 5.9L trucks. The fully built com­pe­ti­tion trans­mis­sion came from Sun­coast Trans­mis­sions and is con­trolled by their TCM 2800 PCS con­troller.

 The CSP5 switch con­trols cus­tom tunes writ­ten by Cal­i­brated Power So­lu­tions and the ex­tra switches con­trol aux­il­iary light­ing in the front and rear bumpers.

 Au­tome­ter fac­tory-match gauges fill the pil­lar pod so Canale can watch EGTS, boost, fuel pres­sure and rail pres­sure.
