I am looking into installing a few performance mods. Like most people I want to spend as little as possible and gain as much HP and torque as possible. Any recommendations? Cold air intake? New ECU? This website has a few things but I'm not sure if it's all junk or not. HYUNDAI VELOSTER : EnginePerformanceChip: Buy Performance Chips for Cars, SUVs, and Trucks..
If you have any suggestions that are under $400, it would be greatly appreciated!
