Another Company is seIling a cheaper tuning system which they say is the best, is it true?

Unless it is a Spider®, then no. There is no other tuning system on the market as advanced as the Spider® no matter what the claims. We have investigated and di-sected the majority of tuning devices on the market and have found none that come close to our products quaIity and functionality. Some of which have been cheaper for a very good reason.
