As I get my car back together and learn how to tune with the wideband and translator pro, I am still thinking about tuning it like I did back in 2002-2003. Start with safe boost and turn it up a little at a time until it knocks or runs lean.
So here is the question... Currently, I am running 23 degrees of timing (up from 19 one degree at a time) and have run 25# of boost (up from 15# one pound or so at a time). All the while cautiously looking for knock or leanness. AFR has been in the low 10's (10.1-10.3). So I settled on the boost and timing where they are and have starting pulling fuel out a few % at a time which REALLY woke the car up. Normally I would do third gear rolling starts to get an idea of whether it would lean out or knock and even though the scanmaster would read as low as 680's, the wideband afr always showed a safe number. All of this is on 93 pump gas. Does this tune sound weird to anyone?? I hear that over 20 psi is risking it on pump gas especially with higher timing. But should I continue to turn it up since it doesn't knock?
PS, I have a set of valve springs ready to go on the car as soon as I can get shop time. Everything else is in my signature. Wideband correction is set for 10.9 but I added a bunch of fuel to keep it safe in the high load range on the TPro until I got to tuning the fuel curve.
