Subject: Re: 900 SPG APC Gauge question

My 86 SPG seems to not like the heat, and is finicky about the octane of the gas I use. On a cool day, with 94 octane, my APC needle makes it all the way to the top of the yellow. On a hot day...using 91 octane...I don't have a hope in hell of achieving full boost. Julian Sweet wrote: > I have a 1990 SPG that I take to a Saab mechanic.
