Not really, pwr steer idle up, a/c idle up, auto anti stall etc are all required for the niceties of a daily driver.... many afm based ecu's strugle without one. Nistune for one is happy to make upwards of 500rwkw but does not like having the iac removed.
if your ecu allows it and your not fussed about having a higher idle than std etc than yes it can be tuned around (mostly map based ecus).
The only people who seem to get good results with these are guys who need to justify the fact they sold it to the customer.... yes we tuned heaps yes they work (like std) would i put one on my own car ... no.
