Default ECU & remap question

Hi folks,

A quick question for the experts.

I have a TEK3'd MY99 which I'm selling.

It was mapped for a full decat & induction kit.

I have replaced the decat with the std exhaust. The car is now running like a

dog.

It feels like the MAF sensor TBH, but this is less than a year old.

I will be replacing the ECU with a std one once I find one.

My question is: Will the std exhaust along with the remapped ECU cause the above

mentioned problems.

Thanks.

it will because the ecu was mapped for a much better flowing exhaust...the standard restrictive item is not suitable for the fuelling that the tek 3 ecu is set for... a standard ecu will work much better

That's what I thought, but the car is fine when cold/cool but gets worse as it warms which made me think it may be the MAF.
