There is a product on the market referred to as an OBDII flash tune, it is marketed under various brands in the UK and Americas (ByteFlash, LiveTune, VR Tune, etc) for several makes and models such as Aston Martin, Jaguar, Lamborghini and others with pricing ranging from $995 to nearly $3000. It remaps BOTH the TCU & ECU for maximum performance and other significant claims such as speed limiter removal, shift points remapped, throttle response remapped, spark timing, AFR remapped, acceleration hesitation removed, faster response from shifter paddles and more.

I have spoken with someone who makes a living doing dyno tunes and he claims this product is better.

I am only looking for individuals who have experience or are familiar with the product. Thank you!

 

Interested in this as well.
Debating 1.5 or 2 lb pulley upgrade and ECU tune. This *might* be a viable alternative.
