Enhanced Automotive Technology Performance "ULTRACHIP" chips:

Time to get your performance chip. Basically it had been said that EAT performance chips are as good as the JC chip... And the M5 EAT chip is better than the JC chip...

You may have not heard about Mark D'Sylva, but he has been developing various performance chips for over 10 years. Mark has been developing embedded systems firmware in assembly language and C for many new products over the last 20 years, and is using these skills to reverse engineer Bosch Motronic units.

Mark has developed code for products such as: BMAC and MPEG-2 satellite receivers, steam autoclaves, video ASICS, various process control and communication systems. Now that he is self-employed, he is focusing more on chip development and sales. I know you may be hesitant in buying something unknown, but these chips have all been tested thoroughly in the last few years. You will definitely be satisfied with the performance increase these chips offer. And on top of it the price is RIGHT..
