Hello,
I'm thinking about doing a turbo but i am not sure the best/cheapest way to get the cars computer to dump more fuel and possiably advance the timing. I want to do one of my Saturns but i heard that their ecu's are hard to work with? I see these Apexi controllers out their, is this standard equiptment to run a turbo correctly? Any and all help is apreciated!
thanks
chad

 

depending on your year vehicle there is a world of options for tuning. if you have a late model gm vehicle then the place to call is trifecta. they will reflash your stock ecm to whatever hp levels you want. those apexi controller only trick the stock ecm and to me there a waste because there limited.

btw: more boost less timing... advancing the timing under boost will produce a boat anchor.
