I self tuned to 27psi with no knock with 14* peak timing with 11.1 a/f ratio on 93 and man does it pull hard. Newborn then came and I could not finish the tune. Fast forward to present day and I am wondering, knowing the fact that 27psi is just close to the outside of the efficiency range on evo 3, should I lower boost to about 22-25 (and deal with creep) and raise more timing or should I stay with psi and raise timing until knock? Mod list is in profile but important ones are built motor, 255hp fp walbro, fic 1150cc, evo 8 Maf and link
Reason I chose to tune to 27psi is because no matter what psi I set it for (22-25) it creeped to 27psi even with map o2 dump and ported turbo inlet and wastegate hole ported.
Thanks
