Ok, the mods will start tomorrow after my CEL issue is resolved. This car runs great, but like every other vehicle in this house, more HP is better. I am going to start with the basics and need a few pointers.

Car: 98 V70 AWD turbo

1) is an ECU swap necessary with a manual boost controller?
2) what is stock boost?
3) how much boost will the stock properly functioning fuel system support?
4) will a 3" exhaust throw a CEL?
5) will a test pipe or gutted cat throw a CEL?
6) how much boost will the bottom end support assuming it is supported correctly?

 

1. No, but an ECU upgrade is a better idea then a MBC any day and safer. Also if you go either route get a real boost gauge installed.

2. Well are you LPT or HPT? If your LPT your running about 5-7 PSI of boost.

3. If your LPT you can boost around 15PSI max.

4. It shouldn't.

5. Probably and not recommended. At least not a gutted CAT. Check your local laws on the legallity of that. Personally I wouldn't do it and don't recommend it. Just do a full 3" mandrel bent system with hi-flow CAT and straight through free flowing muffler such as a BORLA or Magnaflow.

6. 15PSI again is what is safe.

 

anyone heard of these?

sounds to good to be true

 

If it is from E-bay and a resistor looking thing RUN AWAY AS FAST AS YOU CAN!!

 

DO NOT BUY THIS. IT IS CRAP, WONT WORK AND IS A GIMMICK.

 

THANX 4 THAT

 

so a MBC will work and the ECU/Injectors are capable of fueling it until 15PSI?

 

Yes but I would only run about 13 to 14 max.

15.5 is fuel cutoff and believe me you will know it if you hit it.
