Benefits of DBW Over DBC?

The whistle is because you have a chinese throttle body on the engine(snipers are rebranded Alibaba). The chinese IAC port is machined poorly, wrong angle, size, etc. With a brand name one like Edelbrock or Nick Williams... Ive never had a noise.

I definitely agree with this. The IAC port was not only small but very deep and the opening edges were very sharp. I just got a GM 87mm for $40 from the salvage yard works great.

Yea we have purchased many of these and modified several of the ports to quieten them down. Throttle bodies get expensive. 112mm DBW from Kong is over 1k USD. But with big power, cam shafts, air turbulence... the stock stuff wigs out, especially in turbo applications at big boost. Thus switching to cable. I actually went dbw to cable and love every single moment of it. But its great quality and it shows. Big cam, big boost, injector dynamic injectors, nick williams throttle body, stock ecu making north of 1200whp and drives like stock.

Happy to hear everything worked out and youre happy with the results! I know I miss the simplicity of cruise control and throttle closing on WOT shifts!

The throttle will close on an automatic when it up shifts?

Yeah I’m only running 13# as my motor breathes so well. That’s with a 2.45 and 9.1 too.

Some tuning strategies, Yessir! Thats how the new 6/8/10 speeds are staying alive, stock with torque converters making 1000hp.

The tuning strategies are ever evolving.

There was a video on youtube where someone put a camera on a DBW throttle body and showed the flutter leading up to limp mode. Naturally I cant find it.

Holley has similar torque management strategies, but they allow the user to cut the ignition timing during shifts. This is actually quiet effective at limiting the amount of torque that is being applied to the transmission during upshifts.

I see we follow each other on IG. Willing to take a look at my tune? I have a 12.1 Target AFR, 18*
