American Made


The PERFECT HI-VELOCITY LS2, 3 & 7 95MM Mechanical Throttle Body is a great addition to your 2006 and newer LSX engine combination. It converts your LSX engine over to a mechanical throttle linkage by replacing the factory GM electronic throttle body with a much larger and improved airflow design to fully optimize your engine's potential.


NOTICE: This Throttle Body will not work on a 2006 – 2011 GM LS2, 3, or 7 unless
an aftermarket Engine Management System is used. The factory GM computers 
used to run these engines are for Throttle-by-Wire or Electronic Throttle Body’s
ONLY and will not have the functionality needed to run the LS1 IAC(Idle Air 
Control Motor) or LS1 TPS(Throttle Position Sensor). 



PERFECT HI-VELOCITY LS2, 3 & 7 Features:

1) Uses the LS1 mechanical throttle body TPS and IAC from a Camaro or Firebird. The popularity of these engines makes attaining these sensors very simple.

2) Elliptical Blade to allow for superiour drivabilty and throttle response by minimizing the abrupt change in airflow during the first 15 degrees of blade movement or what's commonly referred to as "Tip-In".

3) Manufactured from billet aluminum, black anodized and then polished to a high gloss black finish. Oxidation of these throttle bodys is not a problem.

4) All stainless steel fasteners included along with a stainless steel throttle cable bracket.

ECM Flash Program



This is a basic start and run tune that we only recommend for a near stock application. We will only change the following parameters: delete VATS/PASS-KEY security, cooling fan on/off temperatures, rear end gear ratio, tire size, speed limiter, rpm limiter, idle rpm, and we will adjust the check engine light parameters. If your setup requires any other parameters tuned you will need to locate a local tuner. All ECMs are left unlocked to allow easy access for your tuner.

Step 1: Purchase one of the qualifying part numbers. See below for that list.

Step 2: If your part number is highlighted RED proceed to step 3B. If your part number is highlighted BLACK, proceed to step 3A.

Step 3A: If you have arrived at this step, your harness does not come with an ECM and you must provide one to be flashed. Please reference the manual with your harness to confirm the ECM part number required.

Step 4A: Once you have received your harness, please cut the Barcode label from the box as shown in the picture below.

Step 5A: Package and mail your ECM along with the Barcode label, a copy of your purchase receipt, and your ECM form that you are about to complete. (The address will be provided after you complete the form). We will pay for return ground shipping*. If you request a faster service, you will need to provide a return label.

Step 3B: If you have arrived at this step, your purchase comes with an ECM. You must fill out our ECM form BEFORE your purchase will ship. Proceed to Step 6.

Step 6: Click the “Start Here” button below to fill out our ECM questionnaire.

Step 7: Once we have the ECM, we will use the data from the form to flash the ECM. Then, once it has been flashed we will package the ECM and ship it back to you. If we encounter a question, we will contact you. This process can take 1-3 days.

Step 8: Once you receive your ECM, it is ready to go.


*Note: Our free return shipping is ONLY good for the lower 48 states, via ground UPS. If you are outside of those states, you must provide a return shipping label with your order. If your purchase comes with an ECM, the shipping will be covered via the retailer you purchased from.
