Typically of every car, there is like a certain amount of mods till we need to get our mapping redone. Just curious about how many mods should we consider getting our ecu flashed or a piggyback system.

Currently i'm running MD 5/16 spacer, Ypipe , Ztube w/ K&N.

Would adding HFC make me be running more towards lean side?

do it the next time you feel the urge to get a dyno reading. By then, i'm sure you'll have added enough stuff to warrant a tune to bring it all together with software.

42 (if you have to ask then u dont know, its the answer to everything)

what kind of answer is that. He's asking a legit question. I was wondering the same thing... So if anyone has a legitimate answer please reply.

eh imo this should be done when youre done with your mods. whats the point in tuning your car this week and then adding more mods that will eff with the tuning from this week? lol does that make sense? i ono im tired..

go buy yourself a book and a sense of humor.



OP, if you want a suggestion, get one done after you get headers.

good luck!

im running na and so far i've done HFC, upper plenum, intake, exhaust, pullies etc... if u have a 280 motor then before u go further with anymore intake mods, such as an MREV2 or if u already have the MREV2 a new upper plenum or spacer u will need to adjust and tune ur A/F ratio... this is usually the most time consuming part of a retune and once they do this they just usually take care of the simple stuff like rev limiter, throttle, governor, etc.. go to technosquare once ur done with the majority of ur mods, they'll charge u about 650 for a retune but its well worth the money
