Re: Project XXX AWD WHP Or Bust!
You need a good FPR to run 2 pumps all the time, even some aftermarket ones don't handle 2 pumps at low load perfectly. A lot of people with 2 pump systems have the second one come on at 15 psi or whatever instead of running them all the time.
1G ignition timing with 2G or higher compression is not good. It depends on what was actually in the chip though and what kind of boost the tune was meant for. At 20psi with 8.5:1 compression you might only be able to get away with 11-14 degrees of timing on our normal pump gas, while the stock 1G timing maps would be trying to run 22-24 degrees. It probably would have been lower in a chip that had the timing maps modified though, because the stock 1G ignition timing doesn't work very well even on a stock motor 1G unless you are running low boost or race gas.
