Re: pg7 up from a pm6 worth it?
ok here is the deal... PG7- 7.2k rpm redline
PM6 6.5k rpm redline
The pg7 is a little richer in fuel all around and the ignition is a little fatter also.
the PM6 is well a stock Si ecu you would be better off (i know cuz i have done this) using a 90-91 PM6 with a PM7 chip (JDM) it will be the exact same as a JDM PM7 that is the better way to go and the reason i say this is because with my pg7 and my 90-91 pm6 (stock) i couldnt really tell the difference besides the redline but with the JDM PM7 code in my PM6 it made a HUGE improvement over the stock PM6 if you would like i can supply a JDM STOCK PM7 chip if u have a 90-91 PM6.. its fairly easy to install
