The Apex'i Super AFC isn't the only Fuel Computer on the market.

The HKS Super AFR has a better idle control circuit and is just as easy to tune as the AFC, just doesn't have the fancy display and might be a good idea for those worried about your AFC getting stolen.

Also you might wanna look into the Greddy E-Manage or Perfect Power's SMT-6 - www.perfectpower.com

They have installed them on Neons and Vipers with great sucess and you have more tuning options than available with the Super AFC.

You almost might look into shooting the intercooler with CO2 or injecting nitrous oxide for intercooling and additional horsepower. Nitrous Express has the N-Intercooler and I sell them.
