yup, it's not "cheap" but it's not unreasonable considering DRYBEAR's car is turboed and 5 speed... in his case, keeping tabs on his engine is crucial. DEFI even used to make a VSD boost gauge/turbo timer (http://www.defi-shop.com/product/bt/bt_top.html ), but have discontinued it and it is very hard to find now.
