Granted our grassroots movement doesn't have the shine and bling of something like Hondata, AEM, Zdyne or the like...But it's free to those who want to learn and are capable. Now as for the Rising rate regulator and bigger injector junk....[soap box]Thats just a poor mans way to 1/2 ass supply fuel for boost. It does work but it's a retarded way of adding extra fuel, thats been around since the very early days of F/I. It shouldn't be applied to today's EFI setups....AT ALL.[/soap box] Jacking the distr
ibutor back to retard timing also isn't a very reliable way to account for timing under boost. 6-8 psi of poorly tuned boost can do the same amount of damage as 20psi. Adding more air, your gotta add the right amount of fuel, and compensate the timing properly or you're just asking the engine to grenade on you. An OBD-0 ECU can be chipped with a conservative prog to run boost and ulitize larger injectors....for just about any engine you want for normally under $100. I'm not saying i'll do it, but i'm just saying it can be done.
