Porting is never necessary, but your wasting your money adding performance parts that won't reach their full potential. You'll find few people running a 50mm because it is easily outgrown. A 47mm and 54mm overlap the powerbands making the 50mm almost a waste of money.
Always check the rubber intake to see if it needs porting to the TB.
I asked Cuervo Racing for a map and they offered me the 47mm.
In fact, it is a lot more expensive than here in France.
This company looks super professional.
They sent me a free map.
As a thank you I take the Mod 47mm.
You think I should take bigger?
I would say you're in the -60HP range, so go with the 47mm throttle body. That is a factory throttle body machined 3mm bigger and a new throttle plate to match. You'll need a map adjustment to match.
This is it, I ordered from Cuervo Racing
I wait to receive everything to make all the changes at the same time.
I hope to feel a real improvement.
There’s just the exhaust line that’s already on the 700.
