Joe brought his Chevelle in after dealing with a number of issues with the Holley Sniper system and never being able to get the car to run and drive the way it should.

We spent some time going through the setup, addressing the issues we found, and then getting the calibration sorted out.

The dyno results were also a little surprising. I expected the car to pick up some power with the air cleaner lid removed, but I didn’t expect to see as much of a gain as it did.

Another L83 5.3L truck, this one has the Brian Tooley Racing L8T torque camshaft everything else is stock.

Solid gains over the stock L8T camshaft which is the red line run. Green is stock L83 baseline. All of these runs are 6 speed trucks pulled in 3rd gear.

You can hear that torque cam through the stock exhaust!

Andrew put a BTR Red Hot Camshaft in his Camaro and had us get the calibration squared away for him. I was on the dyno and realized I had company in the back seat while making some hits!

Dialed in Greg’s truck after he installed a Brian Tooley Racing Stage 1 Camshaft.

The truck is an 8-speed pulled in 4th gear. The red run is a stock L83 6-speed pulled in 3rd gear for a baseline. The transmission ratios are fairly close, making it a good comparison.

The truck is completely stock other than the camshaft.

This 5th Gen LS3 Camaro came in with a leaking manifold gasket, and the customer was concerned with how it was running overall. After a baseline on the dyno, it was clear the car was running lean and picking up spark knock on the aggressive calibration.

We replaced the gaskets, plugs and wires then went through the calibration resulting in a much safer AFR, cleaner timing, and picked up power across the entire curve.

Had the opportunity to calibrate this badass clean square body build for Blake, this 408" LS flat out rips.

On the dyno it put down 394 RWHP on 93 octane and 428 RWHP on E65 through the 4L80E, factory transfer case, 4.10 gears, and 33" tires. All pulls were made in 2nd gear.

Big thanks to our friends at Wicked Performance for lending a hand on the Holley as we don't do many often.
