For the 2014+ Impala, Overkill offers tuning through HP Tuners software. For the special $499 pricepoint, you get an HP Tuner suite that you'd buy elsewhere at the same price but you also get Overkill tuning! With it, you get 20+ horsepower gains on 91/93 octane, E85 tuning if yours is flex fuel equipped, improved throttle response and feel, revised transmission shift pattern and feel for a sporty comfortable drive, speed limiter removed and much more.
Most importantly, you get custom tuning at no extra charges. Not only do we have our own calibration revisions for our own throttle body upgrade, ported intake manifold, JacFab intake spacer and more, but you can also provide scans and get multiple revisions, all included in the $499.
You also get a highly resellable HPTuner product whenever you're finished tuning your Impala.
We're pleased to be first to market with our A-Simple-Intake kit for the XTS/Impala/LaCrosse platform. Sometimes what's simple works best, and in this case you can anticipate a 15 horsepower gain from our open cone design that greatly improves airflow to the LFX motor in your Impala, XTS or LaCrosse. A turbocharger grade black silicone elbow connects to a black powdercoated 3.5" MAF housing with high flow air straightener screen to a large black media cone air filter. Its a simple setup with a great look and great performance.
Uses a reducer sleeve to mount to the factory 3" throttle body connection. Simply remove the sleeve for our throttle body upgrade. This system will grow with you!
Overkill is the only company offering a solution to the small 72mm throttle body. This a larger 80mm throttle body (measured at the throttle blade) that'll flow a lot more air. Improves throttle response and lets your LFX V6 sing at higher rpms. Comes with our adapter plate, stainless allen bolts, and some items to help installation. No tuning required however those with Overkill tuning can get a no charge retune with improved throttle sensitivity calibration. Will not work with the factory intake tubing but works great with an Overkill intake setup!
The JacFab intake manifold spacer goes between the upper and lower manifolds, increases runner length and with it mid-range torque. An easy and effective modification that can be done at any point in your modification list. Overkill sells the correct intake manifold spacer for the 2014 Impala LFX intake manifold!
Available in Spring 2016 will be a ported intake manifold, based on a brand new manifold core.
