Anyone have any tips or tricks to make turbos spool faster

( lower RPM)

I am running https://www.precisionturbo.net/turbochargers/factory-upgrade/details/Factory-Upgrade-Turbocharger---Subaru-WRX--STi--Forester/547

Stock top mount intercooler but boost dont come on until about 4500 RPM full boost about 5300. Can advancing the timing at low RPM give me better throttle response?

My advice would be to aim for MBT timing during spool up. You can see a small improvement in spool by targeting a leaner AFR during spool up as this creates more heat in the exhaust system. The difference in spool is likely to only be minor though - Perhaps 100 rpm or thereabouts.
