Tooter manifold / Corolla TB / DC Header / etc....

I think that was meant playfully, not as a real suggestion. At least I meant it that way. Sorry to confuse the issue.

if I remember they were marginal losses, and that was without a 1zz TB. Nothing like what I'm feeling / and not all where I'm feeling it either (I'm also feeling a lack of top end (not that it was a screamer before) )

Hey, you asked. I gave my opinion. Even a marginal loss is not a gain. Possible vacuum leak somewhere, maybe? Have you checked all the connections and listened for leaks?

You might try going back to a stock TB and see if that cleans it up at all. Our manifold accepts either throttle body, I'm not sure about the Tooter.

Remember, you've changed two or more things at once. It's best to change one thing at a time to see what the result is.

I am. It works with both throttle bodies.

lol yeah I was merely jesting. I mean, yeah you'd get power haha, but I know most people don't want to dump 33% of the cost of the car into a supercharger.

I have listened (my family calls me Miracle ears), and to the best of what I hear there weren't any leaks.

Of the areas where there could be a leak (below) they all seemed fine.

-Intake manifold to Head = check
-Throttle body to Intake manifold = check
-Intake piping = check
-Brake booster vacuum line = check (factory line)
-Evap system vacuum line = check (factory line)
-CrankCase vacuum line = check (exact specs as factory, only 1 inch longer)
-CrankCase fresh air line = check (breather)

-Exhaust Manifold to Head = Check
-Exhaust Manifold to downpipe = Check
-O2 sensor = check

I might start with just swapping back the OEM TB (Like many have suggested) and go from there................
