Ok, so here it is. 2002 IS300, 177k miles, double 🐌🐌 set-up off of a supra. Running at 5psi atm, no tune. Have 550cc injectors (not installed yet). Trying to find a shop here in SoCal to tune it, but no one wants to do it. Also need to hook up SAFC2, aem af and defi boost gauges and of course injectors. Anyone know of a shop around LA area? I know it's somewhat unique setup, but I need to get it done. Appreciate any input.
