i was just wondering if this (gtech pro ss) is good for everything it advertises? i mean it lists alot. has anyone used it? or is it a waist?

 

its pretty acurate, but alot of things cause them to be off...

spinning the tires make them read funny, as well as power shifting really hard and spinning the tires.

mine was acurate within 1/10 of a second once i learned to use it right. and HP was about3 off but TQ was WAYY off..it said i had like 340ft lbs when i had 300 ft lbs...
