You are talking out of your hat. I can tell you 100% what Tuner says. That’s a FACT.
Maybe you need to follow the link that Hysteric posted a while back (it was in a different forum but it’s on FABO) and it has (IIRC) a huge amount of Tuner and Shrinker carb info.
Do that and you’ll find they don’t agree with you, because YOU are wrong.
In fact, because it’s a new year I’ll see if I can find it and link it here.
