Ive heard all these stories before, and I run the Gloshifts. Just to be sure I checked their accuracy with a friends Isspros. Mine are dead on with his. So, if it seems like one of the gauges is off, or out of the norm. Compare them with someone you knows "baller status" gauge to see if its off. If its off, glowshift will replace it for free. The pillar kit comes with everything you need. Mine work perfect. Been running them for about a year. Plus when I bought mine I got them on sale, boost 0-60, EGT, and trans temp with a pillar and all wiring for 180 plus 40 shipping. You just cannot beat the affordability. And I know there are 100's of members of the org who run them, they are just scared to speak up. Pop the name Gloshift into google and it will tell you if there are in fact actual recurring issues.
