If you go with a BTM you can lock your timing at 30-32 and have it pull outOriginally Posted by Krwy
1 degree per pound of boost so that it runs good on the bottom end but drops timing to 20-22 at 10 psi. Make sure you have a good strong manifold vacuum/boost reference, don't go thru the vac tree for the BTM signal!
edit: if you lock it at 18-20 it will do alright at WOT, but you will get lousy gas mileage, and may even do damage to catcons if you still have them on there. When running EGR at cruise rpm, the eec can dial up to almost 50 degrees advance! (this is why near-stock Mustangs can make 24-26 mpg on the highway).
