Larger TB or not?
After doing the P&P heads, oversize valves, headers, cams, mufflers, and a dyno tune, I am now considering getting the larger Throttle body. So is it really a needed thing considering the price, wondering if it will return enough peformance gain to make it worth while.
Second, which size would be best for my 2013 103 with 10.5:1 CR? How about the wye behind the TB? Seems to me that would also need to be changed to a bigger bore Then, if I did the change, would I need to change the injectors as well?
And lastly, would it need another dyno tune, or would it be close enough to simply run it with the current tune? Dyno as it is was about 96 HP 113 tq. Just wondering how big a difference it will make to go with the bigger TB or leave well enough alone, and if there is a thing of too much TB?
Illegitimus non carburundum. Or something to that effect. Jack of all trades, master of none.
