What's the inside diamater of the pipe on the new intake? If it's any bigger than stock the MAF will read less air passing by and give less fuel making LESS power.

^ This. You never answered the question about inside diameter. What kit are you running?

The ECU is very particular about air passing the MAF. Deviate from 2.25" inside diameter on the pipe and you'll typically run into problems.

just checked, its 2.32" (59mm) rather than 2.25" (57mm) .... (25.5cm2 over 27.3cm2)
Only a tad bigger, wouldn't Imagen that small a difference will cause a problem would it?

2734mm2 = 59mmŲ
2551.75mm2 = 57mmŲ

That's a 7% jump with no additional fuel.

So today I had another go at sorting it out. Reset the ecu as sujested. It did run better but still no where near right.

This seems to be the problem, I made a restrictor to put inside to reduce the ID of the tube and it helped allot! I still think it was down on power a lil bit.
Ive put it back to standard untill I can remake it with a smaller ID tube or of course get a premade one.

Does anybody know what size ID the aftermarket one is?
