yet another stereo install question (Best Buy, etc.)
I tried that mod before I did my mods. I did not notice anything different with boost pressure. It seemed to come on slightly earlier, but nothing significant. I noticed a bigger difference when I installed my TurboXS HP MBC. The boost came on a lot stronger and a tad bit sooner. Then again, I did the MBC right after I installed my full catless exhaust. Just keep in mind, once you do your DP and exhaust, you will most likely need a MBC to cap the boost creep.
