Fuel cut? boost cut? Problem

HI all,

I have a problem taht i noticed just after i had my 3inch exhaust fitted. When i takeoff hard in 1st or 2nd, my car kinda hesitates (goes like putt putt putt) then goes, it only happens normally at nite when it is in cold weather. I talked to a mate of mine and he seems to think its a fuel cut problem.

His reasoning is, since i got the zaust fitted that creates more boost (even more when its cold weather) and when the ecu detects the overboost it tried to stop it by cutting the amount of fuel going into the injectors. But the weird thing is, i dont have a boost controler or a bleed valve fitted so i thought i was running standard boost.

The only mods i have dun is: Trust Airinx air filter, big frontmount intercooler, 3inch exhaust with a twin dump pipe from the turbo and heavy duty clutch. I took it on a dyno run and got a reading for 177.8kw at the wheels, and there was no hesitation when they did the run because they slowly builtup speed. As i said, the hesitation only really happens at 1st and 2nd when its cold.

what is a way quickly fix this problem? fuel cut defender? boost controler (and turn the boost down)? or get a apexi SAFC??

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
