were you with petrol only?
if you have access to e85, easiest way is to keep stock compression and use that, for easy cheap power
an unrestricted hks sc with 90mm pulley will reach about 0.95-1.1 bar (depending on ambient temp) and with e85 that s easily 400whp
about ecutek yes it s shitty situation, does your smog check include an obd check or they just check for smog in tailpipe?
Because there is a workaround (pm me ) for ecutek to work with everything, but if you then have to go back to a USDM based tune it becomes annoying the conversion
