Not sure if it works, I know caspers electronics makes the same thing, so they probly just ripped off the design from caspers and made it.

 

As always READ CAREFULLY. All you are really getting with that "kit" is an "adjustable" TPS sensor. This is accomplished because the new TPS they include has slotted holes. You can accomplish exactly the same thing, FOR ZERO COST, by opening up the screw holes in the stock TPS sensor so they are slots.

Then there is the question of "will I notice any performance increase"? Not likely. The TPS sensor in the LT1 is not adjustable because the PCM can read the TPS voltage at startup, set that number as "0% TPP" and prorate up to 100% TPP from there. MOST cars do NOT need an adjustment. As long as the closed throttle signal is between 0.20-0.90V, the PCM can handle it. Some people feel they get "faster throttle response" if they start with TPS voltage in the range of 0.50-0.65V, but that is open to question. Almost every stocker I have ever measured is already at 0.65-0.67V.

If you have your heart set on spending $51, at least check your stock TPS sensor voltages before you invest the money.

 

Sounds like a "gimmick" to me.
