You can see all my mods in my sig but i was wondering would i benefit at all from a larger maf. If so what size?

Thanks

You should be fine with the OEM MAF...

The stock MAF pegs (4.99V out which is all the PCM will recognise) at 1220 kg/h air flow. At 4.8V it's 1100 kg/h = 2425 lb/h. If we assume 12.5:1 AFR (n/a, arguably a bit rich) then that 2425 lbs of air will need 194 lbs of fuel to go with it--194 lbs/h of gasoline is 388 HP at 0.5 BSFC (Brake Specific Fuel Consumption, 0.5/HP is generally used for n/a engines).

Running forced induction (11.5:1 AFR and 0.6 BSFC) the stock MAF would support 352 HP at 4.8V

Pegged, at 4.99V out, there would be 2690 lb/h of air--using the same AFR and BSFC as above that would be 430HP n/a, and 390 HP f/i...
