Look, how much plainer can I explain it to you? You can't have the best of both worlds. You are not running a progressive system soooo that means that when your alky comes on it is spraying at full capacity all the time. Now how can you tell me that your car requires the same amount of alcohol at 6 psi than it does at 20 psi? It does'nt most likely your car does not supply enough air to support that large does of alcohol at 6 to whatever psi you would normally see knock. So guess what? Your running rich on fuel and guess what else a rich fuel mixture does? It makes your car a dog out of the hole. Of coarse your performance increases when the alky turns on.....duh....you can run more boost. That has nothing to do with your sluggish performance down low. Remember leaner is meaner. Plus you have Hooker Headers they have large primiary tubes and require lots of exhaust volume to fill them up, so that will add to your slowness out the hole. They are great for making power at the top end but unless you have some serious motor work I dought you have enough horsepower to fill them up at the lower rpms. Which only adds to my point....leaner fuel mixture, hotter exhaust gases, faster exhaust molecules, faster spool times.........= happy camper.
I hope that spells it out for you if not someone else will have to take over.
