Sorry, but there's no shortcut here. You're expecting a computer that thinks it's controlling a stock 225hp 302 with 19lb/hr injectors to control an engine with twice as much power.

If you REALLY want to fix the problem, don't ORDER a chip! Find a good dyno tune shop and get a chip custom burned for your car while being tested on a dyno. I honestly don't get why people will spend $15-$20k on an engine but won't spend $300 to get it turned properly.

I took my lowly 351W to a local tuner and got a custome chip burned. For $300, he fixed my idle and drivability issues AND got me 50hp to boot.
