Hi all,

Got a question about the boost in my 97 sti V3, the boost usually sits at 0.7 bar, but just back from taken the car to get petrol and a quick blast and notice when I put my foot down in 3rd the boost climbed to 1 bar then the car started to hesitate 2/3 times as if it was not getting any/enough fuel and was going to stop, this happen twice

Tried it again in 3rd boost went to 1 bar then fell back to about 0.7 / 0.8 bar but there was no hesisation from what I could feel. advance

Any thoughts guys???

Thanks in advance.

Did the hesitation feel like you were slamming the brakes on?

fuel cut

stupid question here but why would a fuel cut affect the boost???

If fuel cut, how can I get around this, should I be looking at a bigger fuel pump??

Theres loads of threads at the minute on Scoobynet, just do a search!

Basically the ECU is detecting too much boost so it cuts the fuel to the engine to preserve it. It happens more so in the cold weather as your car will boost more!

This is happening to mine at the minute, I've just got a MBA, going to fit it tomorrow and set it at 1bar. This shopuld stop the fuel cut!!!!
