I also had to switch engine managements in the process and ditch the MAF which would only flow up to 20psi before maxing out on the T66. Little things have been upgraded as needed, such as ignition and most recently the Q45 throttebody. I made 632whp @ 27psi with the stock SR20 throttlebody and 110 octane gas.
