Need some advice, so I did a 1nz to 1zz throttle body swap and after successful completion of the swap I did a retune, however my car won't pass 188kmh @ 5500rpm. Before the swap I was going 210kmh at close to 7000rpm. Why is my car limited to that top speed after the swap? NB. This car is a 2016 vitz Gs, mods replaced headers, cold air intake with K&N filter, 2 inch pipe from the resonator. 115hp before mods, 123hp after mods.
