HP Tuners VCM Suite MPVI3 Credit Pro Packages

The legacy continues … and now it is bigger, better, and faster!

Built for enthusiasts and professionals, MPV13 is the fastest most sophisticated OBDII interface device to date, and Pro is the new standard. Take advantage of Pro Feature Set capabilities, like standalone data logging and PROLINK+ compatibility (sold separately) already built in. MPVI3 redefines the limits of speed and control with faster standalone data logging and two times the storage capacity compared to the previous generation. Log more runs (faster) and store more calibrations on your MPVI3, all with the convenience of eliminating your laptop from the equation.

HP Tuners VCM Suite MPVI3 Credit Pro packages equip you with the most inclusive scanning, logging, and calibration, making them the only tool you need in your toolbox. The MPVI3 connects your vehicle's control modules to HP Tuners' VCM Suite software. You can run complete diagnostics, monitor vehicle performance, read from various vehicle control modules, and more in VCM Suite. Optimize your performance, fuel economy, or whatever your vehicle goals may be in VCM Editor with a multitude of defined parameters. When you are ready, license and tune any vehicle currently supported by HP Tuners with the fastest read and write speeds available. Connect, read, edit, write, drive; HP Tuners VCM Suite MPVI3 Credit Pro packages are offered with or without tuning credits.

Your Choice of Camshaft, TSP Spring kit, and Hardened Chromoly Pushrods 

This Package Includes the Following Items: 

• Your Choice of Camshaft
• Includes TSP .660" Dual Spring Kit w/ PAC Racing Polished Springs, Titanium Retainers, Hardened Spring Seats, and New Valve Stem Seals
• Texas Speed Hardened Chromoly Pushrods

We have two options listed for our dual valve spring kits.  The default option will use our PRC integrated one-piece seat and seal that simply pushes in place.  The other option is for the separate two-piece seat and seal that you typically find in any dual valve spring kit.  The two-piece kit will require separate installation of the valve seals after the seats are in place, and it does require a specific tool to make sure that the valve seals are installed properly (i.e. not crooked, torn, or not installed fully).  Our integrated seat and seal will make your installation much easier because it is virtually impossible to install it incorrectly!  You can choose either kit for no additional charge.  We have a picture listed when you select each spring kit so you can see the actual differences in the two kits.

PRC's aftermarket casting LS3/L92/L99 cylinder heads come standard with the following options:

• NEW PRC 13-Degree Valve Angle LS3 Castings
• Improved Piston-to-Valve Clearance For Extra Compression & Larger Camshafts
• Smaller Than Stock Intake Port Volume For Improved Port Velocity
• Manley Stainless 2.185" Intake, 1.60" Exhaust Valves
• Billet Rocker Pedestals
• TSP .660" Dual Spring Kit w/ PAC Valve Springs, Titanium Retainers, Seats, & Seals
• CHE Bronze Guides
• Completely Assembled and Milled to Your Specifications
• 60-68cc Chambers

All PRC cylinder heads are extensively researched and tested. The all-new PRC aftermarket casting LS3 cylinder heads are designed to flow considerably more than a gm ported casting while keeping the port sizes smaller for improved port velocity. The result is a cylinder head that is smaller than a stock GM LS3 port and moves more air than any other ls3 cylinder heads! 

The all new PRC aftermarket casting LS3 heads are the perfect option for customers looking for the ultimate in LS3/L99/L92 cylinder head technology

The PRC aftermarket casting LS3 cylinder heads are available in 2 different configurations: 

• 255cc Runners for max effort stock cube LS2/LS3/L99/L92 engines looking for a 370cfm cylinder head that can be aggressively milled & still keep better than stock p/v
• 260cc Runners For LS3/L99/L92 stroker engines needing a 380cfm+ cylinder head!

The 13-degree valve angle will allow for the ability to run more compression and larger camshafts thanks to additional piston-to-valve clearance!!  

With all PRC cylinder heads, quality and performance are our two highest priorities! In addition to performance, you will not find a better performing set of cylinder heads at this price (cost is for the pair!). Call one of our sales consultants today if you have any questions or if you would like to discuss your specific application. 

TSP's all-new line of LS3 camshafts are the result of our latest round of engine dyno camshaft development using our state-of-the-art Superflow 902 engine dyno. Using a brand new LS3 crate engine, we started from scratch to build the most powerful LS3 camshafts available in the country.  Texas Speed & Performance continues to test and develop new designs to make sure that our customers have the BEST camshafts available!

The Stage 4 235/248 camshaft is the perfect choice for customers wanting the MOST powerful camshaft available that still offers adequate piston-to-valve clearance on a stock short-block.  This TSP camshaft is designed for all-out power and shows gains over the stock camshaft beginning at 3,100 RPM.  The cam will pull really hard from 4,500 RPM up to the 6,600 RPM HP peak. This TSP camshaft makes 93 flywheel HP more than the factory LS3 camshaft! We recommend a minimum stall speed of 3,600 RPM for this camshaft in auto-equipped vehicles for streetability, but it would benefit at the track from a 4,000+ RPM stall speed. This cam is designed for LS2/L76/LS3 engines using L92/LS3 rectangle port cylinder heads!

Stock	--	484 @ 5700	479 @ 4300	399.4	441.4
235/248 111 LSA	93/27	577 @ 6600	506 @ 5400	428.1	467.8

**The factory LS3 camshaft uses a single-bolt cam design, which means one bolt holds the upper timing sprocket on the camshaft.  For LS3 vehicles, you can either go back in with a single-bolt camshaft or convert to the three-bolt camshaft design that the 1997-2006 LS-based vehicles use.  The three-bolt conversion kit will supply the correct 4x upper timing gear to supply the correct camshaft position signal, as well as the ARP camshaft bolt kit that will supply the three required bolts.  We also offer the conversion kit with a complete, upgraded timing set for those wanting to replace the entire set.**

The Stage 3 231/246 camshaft is a great choice for customers wanting a more aggressive camshaft with excellent power gains.  This camshaft is an excellent choice for customers wanting more power than our 229/244 and wanting a bit more of top-end power.  We recommend a minimum stall speed of 3,200 RPM for this camshaft in auto-equipped vehicles. We recommend this camshaft for LS3 or LS2 engines using L92/LS3 rectangle port cylinder heads!
