Another quick question, please. Does the TB look any different from the outside, I.E; does Katech, Weapon X, etc. put their logo on the TB? If not, the only way to determine (Dealer issue) if the porting was done is to remove the inlet tube, and a Dealer would not be inclined to do this as part of any "regular" service. Just curious.

the one I just received from Weapon X has no markings on it. Its my understanding that these TB's from Katech, Weapon X, etc...are not made by them, they come off of factory Z06's, the company ports them out, resells them, takes back in & credits for cores that are returned as customers do their swap out,,,,.... ??? maybe I'm wrong, but that's what I thought since I will get a $ 150 credit when I return my core unit to Weapon X after the swap.

Katech does not require a core. Says new on their web site. I would not want one for my 2017 off of a 2015 with maybe 50K miles. http://store.katechengines.com/lt1lt...body-p487.aspx
very good point, I may want to do a little research b4 installing the Weapon X............

Just ordered one last night Jason. New with no core is why I bought yours in addition to even the shaft machined so nicely! Thanks for shipping it out so quickly today.

Just got off the phone with Weapon X and was assured all their units are new, I misunderstood the core credit, you receive the core credit if you are returning your own TB to have it ported & returned back to you, not buying a new one...........

Put a Katech ported t-body on my 2017 Z06 to get rid of that annoying stumble, it did, feels better at low end too, no check engine lights. Something you really don't want to do to your new car, but the results are WORTH IT, were for me anyway

Old thread but just installed a weapon-x port TB. I have terrible stumbling and got CEL and limp mode. Turned car off and got it out of limp mode but still stumbles and tries to cut out once above 3000 rpm. Know its a Z06 thread, but installed on 2017 GS. Any suggestions? Thanks in advance.
