i have cattmen headers/ypipe and catback and placeracing intake about to go on the car and i know that it is going to run like **** if i dont get something for the air/fuel. i was woundering if i should get the safc2 or just go for the neo, or if i should skip all that and just get a stand alone? any adice/info would be great thanks

 

uhh u should try to just put everything on first and let the stock ecu set the air/fuel.
i believe a lot of people has a bunch and doesnt even tune it with safc2; they put it on their dash for show and it runs fineeee

 

you donated...please use it and search
this has been discussed. check the headers sticky

 

ok sooner thanks and getbig i have never heard of anyone running fine with out tunning after these mods

 

I have a PR intake, Frankencar catback, and cattman y-pipe (which, on a VQ30DE-K has similar gains to the headers) and have had no A/F problems....

I would just bolt them on, reset the ECU (unhook battery for a couple hours) and let the ECU relearn the air mix...

 

thanks also i heard that the emanage really screws up your mid range is this true?

 

How would ANY A/F controller "mess up" your mid range? the only way you could mess up anything in reference with a EU is BAD TUNING....

PLEASE correct me if im wrong....

BTW, i have 2k VI with DEK injectors, PR CAI, Y-pipe, Greddy SP, Test pipe....etc....still havent tuned, and its fine...its my daily driver...Im waiting to install my EU, im just lazy....but with just headers and an intake i doubt tuning is THAT detrimental....Get it installed and c how it runs...the stock ECU can compensate more than you would think....
