Seen way to many FMS chips fail, poor quality from what ive seen. When they work they are impressive though!
haven't seen or heard about it myself. but I bet it happens. so far Ive had 2 edge drag comps fail and my edge ez kicked the bucket 2 weeks ago.so I can't say Ive had the best of luck with edge stuff. smarty was reliable but had weird throttling issues from time to time,with a new vp44 and tps. not to mention after years of driving with it installed on sw8 i could really start to feel when the fueling just stopped and the top end was no different than a stock truck.my buddy on the otherhand has had a juice with attitude and it has been bullet proof.like all add on boxes it doesn't hit hard on the bottom like the smarty but has smooth power from 1200 rpms and up. anyone need a smarty for a vp truck?
