ok im starting to do a rebuild and i want to get some more power and im wondering how far can the stock ecu go because what i want to do is a head port and polish and cumbustion chamber polish. will i run into any problems like fuel injectors misfire
Thanks Jose-

For naturally aspirated, the ecu can calibrate a little. When you do a modification like that though you'll gain best results with some kind of tune.

i know tuning it would get me the best results. the reason i ask is because i want to do the port and polish then wait a couple of months till i have the cash to get it tuned.will it be drivable or DD with just a stock tune
Thanks Jose

It should be fine with the stock ECU the maf should pick up the added air flow; the stock 240sx maf is rated up to 190hp I believe.
