Nick Williams TB Internals and base tune Holley Term X Max

[no_go nico]

Lets see if Im asking this correctly, when using the Nick Williams TB on a Holley Terminator X Max which TB should be selected from the drop down for initial base tune? I was told LS3 but does anyone know the number sequence? Thank you

Whichever TB the engine is supposed to have from GM. I'm using a NW102 on my LSA, so I used the factory ZL1 part number. It's going to take some adjusting of the actual TB table to get it to idle down too FYI.

If I am using the Holley sniper intake on a brand new engine build, is there a factory TB? For example, I am building a LS7 from scratch

Which NW throttle body are you using, exactly?

The newest 103mm DBW set up: https://www.summitracing.com/parts/nwp-sd103bk

I would use 12629992 in the software.

Right on! we're going to make a dyno pull tomorrow using the NW103 and a stock GM 92mm and see if theres any significant power gains. Once the engine is in the car, I'll be reaching out to you for a tune.

Sounds good!

Looking forward to the results. I suspect you will see some gains, but probably not more than 10hp

If the power gains are minimal, would you recommend the 92mm over the 103mm for drivability? Its a DBW set up so I think I read it's a little more streetable then a cable driven TB...

It's an expensive TB, so if the gains are minimal, I'd sell it and use a stock TB. The dyno tuning will help. Presumably whoever is doing it will optimize the spark table...At least at WOT.

This is the shop I got my package from. They'll be the ones to tune it also.

that’s cool +51hp/40tq is solid gains. I’d imagine a lot of this stuff is application specific. I’ll post my dyno numbers tomorrow with both TB’s. Thanks for sharing.
