Meyer Performance's Shop Truck

Published in the December 2010 Issue December 2010 Duramax, Spotlight

DuramaxTyler Meyer is a walking example of how diesel performance has grown over the past decade. Meyer began selling diesel performance parts and accessories online back in 2007. He made a name for himself by creating a big presence on several diesel forums and putting a lot of time into getting the Quadzilla tuners to make a Duramax rip.

When the 2008-generation diesels hit the market in mid-'07, the DPF-delete kits really took off. Meyer rode the wave and eventually opened a home-based shop in 2009.

He built up his home-based business to the point that he needed to move into a full storefront facility just a year later. Meyer opened the doors of Meyer Performance in a new shop in Franklin, IN, in April of 2010. The new shop features a three-truck bay with a hoist. Meyer is offering full diesel performance services. And Meyer Performance also handles custom fabrication, specializing in traction bars, 4-link systems, cages and anything for the off-road Jeep guys.

Meyer says his neck of the woods is primarily Dodge country. There are even more second-generation Ford diesels running around than Chevy diesels. He says EGR delete kits for the 6.0L Power Stroke have been very popular. But seeing mostly Dodges and Fords has left the door open for some Chevy testing.

And what's a shop without a shop truck? Meyer Performance's 2007.5 Chevy Duramax LMM has seen more than its fair share of test parts.

Meyer deleted the DPF system right off the bat when the truck had 2,000 miles. It started out with an MBRP LBZ 5-inch exhaust system. This was back before anyone had programs to turn off the DPF sensors. Meyer's LMM ran the LBZ exhaust with no DPF and without a tuner initially. The truck ran fine, throwing regen-related codes, but never went into limp mode. Meyer drove it for a few thousand miles before the technology to turn the sensors off hit the market.

Meyer installed a Quadzilla tuner on the LMM, finally being able to turn off the DPF sensors. He says it was a great day to have a tuner and not have codes anymore.

Meyer soon after installed an AirDog 150 lift pump, then a BD Power driver's side exhaust manifold. The stock manifold has an indent in it to provide unnecessary clearance for the steering shaft. The indent creates a hot spot in the manifold, which is eliminated with the BD Power manifold.

Meyer pulled out the Quadzilla and tuned the LMM with a Hot + 2 programmer from Pacific Performance Engineering. Meyer says the truck ran great with good power, but lacked bottom end response. Soon thereafter, Meyer became a beta tester for the Edge Products' Race Evolution tuner. He ran that for about a year. Later, he also did beta testing for the Edge CTS unit.

As the power levels crept up, the need arose to upgrade the Allison transmission. Meyer built the transmission with a Sun Coast Stage IV kit and a 1055 torque converter.

With a solid powertrain, Meyer turned his attention back to horsepower. When Garrett released the 4094VVT drop-in replacement turbo for the Duramax, Meyer got his hands on one. He says he was looking at either Industrial Injection's compound kit or the Garrett 4094VVT. Todd Fogler, one of Meyer's customers, installed the Industrial compounds on his LMM, so Meyer went with the drop-in Garrett. He installed the 4094VVT charger, along with a Diamond Eye 3-inch round downpipe, in September 2009. Meyer was impressed with the new charger. To maximize its potential, Meyer went to Nick at Duramax Tuner and tuned the LMM with EFI Live.

When we saw Meyer's LMM in Franklin, IN, back in May, the truck still had the stock CP3 pump. Meyer plans to upgrade either to a Wicked modified CP3 or go with twin CP3s.

And what's a Duramax without a few of the basics, like a PPE ported rail fitting and PPE race valve in the fuel rail. Meyer's truck has both, along with an AFE intercooler tube.

As far as being a shop truck, the LMM has seen a Banks cold air intake and an S&B intake, which it currently has.

It's had everything from a 6-inch stack to 4-inch dual exhaust and its current Magnaflow 5-inch single exhaust system. Meyer says that if a customer calls and asks about how one exhaust system sounds compared to another, he can tell them first-hand instead of saying "well, we put one on a customer's truck and it sounded real nice as he drove away."

Inside the LMM, Meyer has Autometer Sport Comp II gauges for boost, exhaust gas temp and drive pressure (tapped into the BD exhaust manifold).

The clean, white regular cab runs Diamo 18kt wheels with 275/65R18 tires.

Meyer's plans for the truck include a full engine build with cut and coated LLY pistons by SoCal Diesel and Crower rods. Once that's done, he plans to build his own compound kit with the 4094 over an S480 charger. He'll also throw in a set of 60-over injectors to get the fuel flowing through the new engine.
