Over a decade later and I still see people asking about performance chips for their Saturns… there isn’t a real one.. honestly there isn’t. People continue to throw money away on them for some reason too… If you want to tune yours the best way is via megasquirt standalone system.. There is a ton of support for it on http://www.sixthsphere.com and you can buy an assembled one and wiring it into your car in about an hour. Good for turbo, NA, nitrous, supercharged, anything… it’s good for more than Saturn too so if you buy it and move to another platform you can bring it with.
Unquestionably the best, I’ve had them on several of my Saturns over the years… buy them.
The 3G SC2 decided to eject a rod late last summer so I no longer have it. I’ve recently replaced it with a 1995 Saturn SW2 with leather, and manual transmission.
I’ll throw up some pictures of the engine carnage from the last one when I get time.
