Just some ?'s
 

I have a apexi N1 exhaust, apexi power intake, and now a downpipe...would the power fc be the smartest mod to get next or what others should i consider? and where does my boost gauge and A/F gauge plug into? and would installing a radiator or intercooler need the power fc?

You should get a pfc next, and you dont need one to install a radiator or intercooler, and those are nice to have. You should get a pfc soon, since your stock comp. is prob going crazy, and if you want to get a midepipe you can overboost and thats not healthy!

nice pic mako, that the carbon creations rx7? sorry for post hogging

You probably are getting some boost spiking right now...so you either need some type of ecu upgrade, or a boost controller to keep that boost at safe levels.

the af gauge dosent "plug" into anything... you have to wire it in... and im guessing you got one of the autometer ones with the pretty colors? it does absolutly nothing, sell it and get a real one or just save your money.

you wouldnt need a PFC for a new radiator but you would for a FMIC. You have pretty much reached your limit w/ a stock ECU.

K thanks guys

i would probably get a good boost controller next & a gauge if u don't have one. i have been running intake, dp, hiflo, & catback for 5-6months now w/ no problem, but i wouldn't take the car any further than that without a pfc or some kinda ecu upgrade. i do have a boost controller though and i have never seen a spike.

A boost gauge is a must...i didn't understand if you have one or not...its a big possibility your spiking 12+ with the mods you have now..btwvYou can always keep the stock radiator with a fmic
