This package will give you more than enough power to break into the 10s at the drag strip! This will handle most lightly modded and naturally aspirated cars as well as even a lot of the boosted cars you might be having troubles with. Even the stage 3 package is very streetable, so don't be worried about losing the civility of your 2014+ C7 Corvette Stingray!

This package is good for 125-150 HP increase and addresses a high performance motor's air ingestion, reduces the restrictions at the cylinders through the heads, and the headers and high flow collector help to evacuate the exhaust gases!

The weapon X4 package option 1 includes:

Halltech Intake - replaces the factory air box with an open style air filter that will still block off the engine bay heat.
weaponX ported 87mm throttlebody - allows better air flowing into the manifold. ($150 Core Charge refunded upon return of yours unless you wish to keep both).
Stage 1 cam kit - Stage 1 kit retains the factory AFM; however, VVT is kept with both. Kit also includes billet timing chain, cam phase limiter, hardened pushrods, .660 lift double springs, titanium locks, and retainers.
Stage 1 LT1-350 ported cylinder heads - the LT1 CNC ported gain nearly 40 CFM over the factory 295 CFM cylinder heads. Can mill the heads .020 for increased CR as well if requested.
ATI Balancer - replaces heavy factory balancer (specify Z51 or non in notes).
American Racing Headers with cats - 1-7/8" primaries and 3" x pipe to connect to factory exhaust.
Catch can - goes in-line with the stock PCV system to keep oil from being ingested in the motor. Direct injection is much more prone to power robbing oily residue build up due to the positioning of the fuel injectors. Keep your motor running at optimal potential.
Instructions for installation on all parts for your shop or you DIY guys.
