ive just had a a custom code stage 2 remap and i installed a boost gauge and was not happy with the boost or the performance so i read a bit about mafs affecting performance, so this morning i unplugged the maf and although it ran a bit crap when i booted it it was smoothe and a lot more powerfull and the boost was hitting 20 psi where before it would only just get 16. I have ordered a new maf. My question is when it was mapped the maf must have been faulty it was only last week so if it now hits 20 psi then will it be lean when i fit the new maf
