Ok so, im runnin an J/R supercharger on a d16a6 (91 crx si) and it runs 6psi and its working great but i want more out of it. I've talked to the techs up at jackson racing and they have stopped production on the boost upgrade but they so to use a 92 civic crank pulley with their 3.0 pulley and it should run me roughly 8-9 psi. for fuel they suggested larger matched injectors and adjustable fuel rail reguator along with a high flow fuel pump. this all is fine with me but my question is: what engine manage system would i be able to tune suffiecently so that im runnin safe? any one does this b4? what works?what doesnt?
