perhaps not....for you
i can say that the mapping on my current chip (msd) is better than the old power engineering chip. and as it seems my lambda sensor is faulty, i am still returning slightly better fuel economy without the closed loop
it can only get better with.
some of these other chips on the market massively overfuel and people just expect it
