Remind me not to use your mapper if he told you to heat wrap to stop a leak

But it could just be the car, not every car is the same, it could also be the quality of the mods, so many variables to take into consideration.

As tony say's,
in the world of modding 1+1+1 does not always = 3,. i would be talking to the mapper as he will know what was not right.

My bet, its the clutch. Same thing happened to me a few months ago, turned out it was the clutch. There was no slip when driving but when it was taken out the friction plates were shot! Replced with Exedy racing Pink clutch, map tweek and all good now.

I'd be disappointed with those figures on that turbo. Is your mapper a known Subaru mapper off here or one of the new breed of dabblers. Not saying it's a mapping issue,as any issues on the car will effect the result,but one of the mappers on SNet with expert knowledge of these cars will usually get the best result.

Some just don't give the figures others do BUT 340 torque is very low for the SC46 even on a 2 litre

I'm sure he will be able to point you in the right direction then.Has he looked over your mods to make sure everything is as it should be.

To be fair, maybe you should of talked to the mapper before posting up....We all know this kind of thread always turns into a mapper witch hunt.
