2g pistons and spool time

[want_a_gsx]

those of you out there that have 2g pistons in a 1g motor, how much of a difference did you notice in your spool? how much were you boostin? what rpm did it hit full spool w/ what turbo?

yeah just gonna get eprom and keydiver. should do the trick...

what are the downsides of having 2g timing maps instead of the stock 1g timing?

To be honest 2g maps are much better for tuning than 1g maps.
They are safer and allow a lot more boost in the long run.
Stock 1g maps are pretty high, thats why the compression change is so crucial
like how jayrolla is having trouble on even just 12psi of boost with 2g pistons and those maps. Hes actually the one who originally told me his problems with 2g pistons and knock
and convinced me to get chipped.
Looking back though I dont think the 2g pistons are necessary.
