Jim, great run, I can't imagine going that fast, especially on a stock cam and heads. Could you tell me more about that Extender Extreme? I have the Extender chip and Trans +, and will be upgrading turbo and converter, and would be interested in how this works. I guess the regular Extender relys on preset fuel curves (with Trans + curve adjustments available), and the Extreme allows the ECM to recognize MAF readings and adjust fueling. Is that correct and does this involve a modified ECM also?
