I love tax returns! I live here in Oregon, about 100 miles south of Matrix Engineering in Portland, and in early February, I am going to get chipped. They offer a GIAC chip for $400 with a $75 soldering and installation fee, and they recommend the diverter valve for $135 and installation for that is $23. Then there is also the chip switcher available for $200, with an additional program (race, valet, etc) for $100. Total for the whole thing would be around $933, or without the chip switcher it would be $633. Is the chip switcher worth the $200(300) dollars? Who here has the chip switcher and how well does it work? Trying to figure out if the extra money would be justified or not. Thanks for any imput.
