tuning twice a year???
 

i meet a tuner who told me turboed cars suppose get tune twice a year. once in spring time and once in mid summer. is that true? i know climate changes specially in canada. but is it true what he is telling me? thx

no....if the tuning software he uses is actually good and he knows what he is doing the software should be able to make proper corrections for temperature changes.

but sometimes its not 100% perfect so some minor touch-up's to the tune would be necessary if you feel the engine is not running right with drastic temperature changes.
