Ok so bought a vl turbo off a mate car was running perfect my mate never had a problem.. the problem im having now is when car is cold car runs fine comes on boost hard but when car is at running temp and you put your foot down it will have a flat spot i have checked the plugs car is running to lean i have changed fuel pressure regs stil the same also changed dizzy the car is running standard turbo setup front mount cooler turbo injectors and standard non turbo ecu i have tried a vlt ecu but wont hold idle go to accelerate nothing car dies out any help would be great thanks ---------- Post added 01-06-17 at 17:54 ---------- ????

I had CAS issues that did this many moons ago and would only happen when hot. Early on I even paid for a tow truck after it dying in Lygon St. Get it home and off the truck and it started grrrr.

yeah CAS is a heat issue however they normally die completely not flat spot. i wonder if you have a fuel delivery issue is it leaning out? boost leak? could be anything but a cas is a fair start.

I have changed the dizzy (near new) have changed coil,leads,afm car is running lean

Dizzy arcing out on cooler pipe when under load ????

The silicon hose is just touching one of the leads

Put in garage, start car, turn lights off, rev guts outta it see if any arcing

Tried that the other night couldnt find anything it happens when under load
