I just purchased a memcal programmer and hope to do some tuning of a supercharged ecotec running 9psi. Just wondering if anyone would be kind enough to post up some graphs or maps of ignition timing curves when running boost. I have heard of people using standard maps with 9psi intercooled.. Surly that is not possible?!? I also looked into using a L67 map but this has more timing than the L36. How could that be possible?
