from what i understand, when you put a downpipe, cat-back and intake im gonna have to get an ecu upgrade. what if i put a manual style boost controller on an keep it at 10psi until i get a power fc, will that keep everything in check because im not going past stock boost levels? sorry if this sounds stupid, i just wanna know.

 

Before i upgraded to single turbo , i had a 3" feed downpipe , 3" midpipe and a hks rear muffler and hks pod filters with stock ecu . it never over boosted and fuel cut , but i think it went higher than 10psi . But i did use a blitz boost controller .

 

so then i should be fine with a boost controller and those mods until i get an ecu.

 

yeah basically you can almost do anything, as long as you have the stock turbos, and keep em under 10psi

 

people dont usually talk aobut ecu upgrade until the catalytic converters are removed

 

Just get a boost controller and keep the stock midpipe and you should be fine.

 

i dont even see the point in getting a boost controller if you're planning to just do those upgrades. if you're not planning to get rid of the midpipe and just do downpipe, intake and catback.... unless you have some vaccuum problems.. you have no reason for your car to go over 10lbs anyway

 

Its probably going to spike after transition to 11-12 with a dp, cb, and intake. That may be more of a wastegate problem than the stock ecu not able to open up the solenoids quick enough to handle the extra flow.

 

thanks for all your input guys. i finally figured out what im gonna be doing with this car. i'll just start with the reliability mods for now and when the time comes, i'll start adding some power.
