wavetrac has lifetime guarantee too.
The biggest difference i have noticed so far is when you pull away in first and second - get the power down so much better and in the wet esp only comes on if you really try to smash it in 1st. not tried too much powering out of corners yet as am easing myself in slowly.
the only one which comes with the fitting bolts is the peloquin as supplied by BDM so that it the most cost effective option.
End of day = they all work well whichever one you go for so it depends on which tuner you want to use and what they stock/recommend.
