Typically, a hydraulic lifter is limited to a certain rpm by the incorrect position of the lifter's internal piston, as the lifter "pumps up." This issue wasn't as prevalent in the past, but with the new aggressive cam profiles, higher spring pressures, and the ever-growing need for more rpm, the older generation of hydraulic lifters just won't cut it. Comp Cams knows this and has released the new Short Travel Race Hydraulic Roller Lifters, using a patent-pending design to maximize performance at higher engine speeds. Not only have they improved internally, but the exterior also features a REM-finish and is black-oxide coated to reduce surface friction, oil temperature, and wear. You can get these lifters for almost any GM application, including the LS1/LS2/LSX and Warhawk.

The 2.0L turbo motor found in the Cobalt SS, Pontiac Solstice GXP, Saturn Sky Redline, and HHR SS is a secret favorite of ours. Luckily, the folks over at Superchips also see the potential of these engines and have just released their newest handheld tuner, the Flashpaq. With gains up to 60.8 hp and 79.8 lb-ft of torque (on a manual HHR SS), this is one mod you must consider doing. Not only do you pick up power, but Superchips also tells us that the tune provides enhanced throttle response, optimized shift points, and noticeable driveability improvements. Like all other Flashpaq models, it also features the ability to read and check codes, display real-time vehicle sensor outputs, data log, 0-60 and quarter-mile times, and adjust the speed and rev limiter.

Low-Profile Noise Maker
If you have ever looked under a late-model GM, you know that space is a pretty serious issue. Now, thanks to QTP, you can enjoy the fun of an electronic cutout, without giving up much-needed ground clearance. The new, oval design fits anything from a 2.25-inch pipe all the way up to 3-inchers and features a CNC'd aluminum body and stainless steel butterfly. Of course, like the traditional units, these cutouts come complete with a high-torque DC gear-driven motor for reliable operation and come wired with weathertight connectors for an easy install. You can use the regular illuminated switch, or opt for the digital controller, which allows you to preset different opening percentages.

Leaving nothing alone, the mad scientists at HP Tuners have already unlocked the 2010 Camaro computer and the amount of control is staggering. Along with the usual tuning controls found in HP Tuners, the new software also contains over 450 new parameters for the 6L80E transmission, full control of the Displacement-on-Demand, and the variable cam phasing found on the L99 engine. Of course, for the LS3/6060 crowd, you still get all of the hardware and software controls you are used to with HP Tuners, including Real Time Tuning (RTT), the ability to use 1-bar, 2-bar, and 3-bar speed density tuning, and enhanced data logging. If you own a 2010 Camaro and plan on doing some upgrades, look into finding a qualified tuner using this software or check with HP Tuners to get your own copy.
