    Turbo Timing ?

    I’m new to HP Tuner so bear with me. I have C6 Corvette 402 with APS TT. Motor is build to handle 20 psi. I just change from LS2 edit to HP Tuner. I am working on the map. I’m using E-Boost2 controlling psi. At 8-9psi timing is 18° if I go to 13-14 psi I get 3,5° Knock retard. Well I need to need to change the timing table to max 13° or is this ok ? Lets say I like to leave timing at 18° do to normally 9psi is enough power and I would load different map for high boost with max timing at 13° is this the way to go?
