boost

if you tune the s/c, can the boost be set to 8 or 9 and still be safe or whats the highest to set it without blowing it up in a couple of months, thanks

Been running the TRD S/C on 9PSI and 88 octane for over a year and a half; no probs on TRD ECM tune. Just recently installed an e-manage to higher. 9PSI is your safe limit on pump gas.

i could run 9 psi with 93 o, what about 10? If trd installs it, how do up the boost and where?
thanks

Car runs better on 89octane w/ 9PSI. You could run 10PSI with 93octane and be OK, but on 100F+ days you need to add some good octane boost. Boost is changed by changing the S/C pulley size.
