wen i change my turbo on my wrx 03 will i have to change the maf sensor

 

No matey,,, but a remap will be need add if it not the same turbo.......

 

If you are swapping like for like then unless your MAF is faulty no need to replace it. However if you are uprating your turbo you will need a remap which will usually get rid of the MAF, but you will need to speak to your mapper about this.

 

Iam putting an TD05 on so yea i know i need a remap, so far the bits ive got ready to go r, headers,full decat, hks air filter,top mount intercooler,pink injectors,3 port & just looking for a turbo
