Tune Change for 75MM TB Upgrade

[Silvergto2]

I am gathering parts / money to eventually upgrade my stock air intake to the KB Big Tube kit with the exception of the 75MM TB which I just got at a great deal today. If I were to install the 75MM Throttle body now with the stock MAF and stock intake, would I need to worry about messing up the KB Tune that I am currently running? Would the 75 MM TB make any performance difference with the stock intake and MAF? I also want to confirm that I can purchase the big tube with without the TB. Thanks.

i dont think that the bigger tb will make a big difference with your current set up. Not worth maybe messing up your tune. wait for the whole set up and get a new tune.

while i dont think it will throw your tune too much to do damage, it will effect the air comming in which will throw the tune a bit. not worth the risk in my opinion

I'd just wait also. One you will feel more of a kick in power if you do it all together and two its not worth something freakishly wrong happening.

you shouldnt need a retune with a 75mm t body if you went to an intake or long tube headders then i would get a retune but i wouldnt loose sleep over it
