Hi LSM , I am not challenging the claimed figures or the power increase , what I am worried about is if it is running a safe Air Fuel ratio (AFR) mix as the standard would run ? . Who knows it may ? But I haven't seen any back to back before and after tune figures to compare results .
Maybe I am just being extra cautious as I have just spent £77k on a car .. And $500 on a tune , which does sell for around $2000 elsewhere .
I am sure many people would like to ask the question , is my car safe with these tunes as no one has actually cracked the ecu yet?
