#4010, "portfueler tuning/AF and boost controller"


          

hey guys whats up. im finally done moving, and would like to get my ride tuned better. id like to start boosting to 20 psi +, but ill soon need some timing control, so for now ill stay @ 15 psi.

setup basics s20G @15 psi
Portfueler
Built bottom 8.8:1
91 octane (its all we got lol)

so ive been playing with the split sec software, and im trying to tune the car via my wideband (aem uego). ive had to take off ~20% and @ wot i still bogg, and my WB is still rich as hell.

question 1: should i keep reducing the whole map percentage until my wot afr is ~11.5 or what? as i spool @ wot, should my afr be 11.5 across ?

question 2: should i keep playing witht the software until im at a good tune, and then add my EBC ( PROFEC B ii), and then will i need to re-tune since my boost will be doing different things at different rpms?

id love to dyno, but thats really not an option as of now, im just looking for a good street tune. thanx for the help guys.

Ya thats what i'm going to do. Just going to keep playing with the software until i get it 12.0 across the board. Only reason I am going 12.0 on A/F is that my friends srt-4 with portfueler that i tuned for 11.5, 11.8, and 12.0 had highest HP at 12.0 which does make sense. +17hp over 11.5 A/F. I would put in boost controller now and tune with it since you can adjust boost and tune accordingly to each psi since you can set it to 15 psi, tune it to A/F you want, up it to 15.5,16psi, 16.5psi, 17psi...... and so on. As for timing control, the people on here have said, as i have also asked before, to use no timing control other than water/meth injection. I was going to use MSD DIS-2 but now i have an AEM water injection kit. Comes with three different nozzle jets. 150-300hp nozzle, 300-450hp and 450-600hp nozzle. I'm going to be using the 450-600hp nozzle. I'll be boosting 26psi with portfueler, port/polished head, cams, and built bottom end obviously. So i'll be 500ish HP i'm assuming, I'll up it to 28psi maybe to get over 500hp. As far as tuning, I am not going to have someone do it, I'm doin it myself as it does not take a rocket scientist to figure out the portfueler.
