Initial tune for homebuilt turbo system I have a turbo system I built. It’s basically a variation off the phamspeed budget one. It looks kind of ugly, but functional. The setup uses the stock intake manifolds, and has the turbo blowing thru the MAF into the engine.
My question is, where should I start in HPtuners for my turbo?
Here are my thoughts on this:
In the "Power Enrich Fuel Multiplier vs RPM" I should bump up all those numbers to command a 10.5:1 starting point. (That means I put a 4.2 in there, right?)
In the main spark tables, I’ll pull back 3* of timing over the entire width of the table from xx g/cyl and up... my only question there is, where would I really need to start pulling timing out at?
What else should I do to start with? The engine is all stock other then the turbo setup. The car is a 2002 SS.
