Can't find the info anywhere. I found at least two different companies that make 60mm and 62mm TB and want to know if there's a huge difference in size.

Stock TB is 55mm. May not sound like a lot, but some are saying they dyno'd a 10HP gain with a 62mm TB. Also, they state that the throttle lag is gone.

Would the computer need a reflash(tune) with a bigger TB like a CAI needs, or should it be good to go after install?

Installed a Motoblue billet 60mm TB. care drove fine for 3 days then went into limp home mode after I went WOT. I had a custom tune before I put on the TB and before I put on the Corsa exhaust, I reinstalled the factory TB and left on the Corsas. No problems since. I also have a C&L CAI which was installed before the tune. Therefore, unless the Moto TB is defective (which Im pretty sure it is not), a tune is needed after a TB upgrade. Next time at the dyno im gonna reinstall the 60mm and find the truth

Asked Lee from C and L this morning about the BBK or other Tb's for the 05 and up and he said that I would not need to tune any for the TB. BBK is coming out with a 62mm at the end of September and there are a few on the market already.

I think he said the stock is 55mm
