I recently was working on a 2006 awd SS, I installed a 3600 tci converter, pacesetter long tubes, SLP cat back, 160 thermostat, air intake, proton nitrous kit and NGK tr6 plugs. The customer wanted the evap turned off, and his governor set at 160. I tuned the shift points, dropped the timing a little, turned off evap, and changed the thermostat settings and turned off rear o2s and bumped up the shutoff.
Now he is having his evap light still pop on as it did before, and thermostat light. Can anyone give me some information as of what's going on here?
Thanks.
