Max superchip timing in a Supercharged application
Mike, what is the max timing you would recommend for a Gen II Lightning? I know a lot of variables are involved but is their a general range? What is stock timing in a 2002? Thanks.

Hi John,
There is no one set figure of course, as there are *huge* variables, such as boost level, modifications, fuel quality the vehicle owner has access to, load, etc.
We don't use a set amount of timing @ WOT in our Lightning programs here at Performance. Instead, the PCM program is set up so that the PCM can *continue* to properly respond to load even with 15, 16, & 17 PSI boost levels on the stock blower (and 25+ PSI on big blowers). That way, you get power gain while even at WOT the timing will still vary based on actual load (& everything else).
Once a few more degrees of timing have been added to the stock program, the answer for more power is not to add more timing (unless the engine is being tuned for something like 100 octane unleaded racing gas) or to lean out the A/F; the answer for even more power is to more mechanical *modifications*, and the chip's job is to properly tune the combination.
