a turbo timer keeps your ignition running even after you've turned off the key for a preset amount of time depending on driving time and style to allow the turbo to cool back to a normal level before ceasing oil flw to it. a blow off releases psi when the throttle plate is closed to reduce/prevent backspin compressor surge ( imagine throwing your trans from 4th to reverse.. lol) the wastegate regulates boost pressure and spike, boost spike is when the turbo boosts past a preset point becuase the Wastgate cant dump quickly enoug, i think his is one of the last terms im still fuzzy on. but a downpipe should be done with a diff exhuast, but that will reduce turbo lag, and increase your turbo's potential to a certain point. a boost controller helps works with a wastegate by telling it when to open, close, intsead of just the spring in the wastgate. that help? haha and ive never owned a turbo car, but ima own 3 sooner or later guna boost my xb, 2jz swap my ranchero, and get the turbo supra lmao.
