I am entering the forced induction world for more power on an 04 Gto Ls1 setup that I am putting in my 93 Blazer with a TVS 1900 supercharger. The only issue I am having is I installed a 2 bar Tmap sensor (GM P/N:90423637) and my temp sensor reading is way off and map volts will not go higher than 2.3 volts even with KOEO. Is this the wrong part and if it is which one is the right one? Thanks for help guys.
