Hey everyone...so, since it has been so hard to find any info on these 2 mods going together, I wanted to share my results on here for whomever encounters this in the future.
I did a visual inspection of the butterfly valve in the BBK 73mm throttle body to make sure the valve does not hit any obstruction when mounted with the AIRIAD POWERAID SPACER (per airaid customer service suggestion...)...none whatsoever, actually they fit together quite nicely despite the smaller diameter of the spacer which is built to fit the OEM stock throttle body.
I installed it, reset the KAM in the computer using the SCT tuner...this way it clears all the computer memory and starts fresh.
I tried the car and was really impressed...now, I know there is a lot of anti-spacer "save your money for something else" attitude out there...but my issue with these engines is in the low end, where they suffer a little before they get up there and thrive...so my intention was to resolve that.
I swear to God it's a beauty...now perhaps it's a combination of all the mods I have (who the heck knows right ?), I listed them below...but with this spacer on I am feeling :
1. Far better throttle response than before, the car is really aggressive
2. Definite push on the low end that was NOT there before and it gets up high far faster than previously
3. The sound is wonderful...there's that whistle that almost emulates a turbo.
No check engine
light, no DTCs from the computer...I checked...
so verdict ? Whetehr it's a combo of my mods I cannot say, but after being wary of the compatibility between the increased throttle body mod (BBK 73mm) and the POWERAID SPACER that is built for the stock throttle body diameter; I can safely say this worked like a friggin' charm for me.
BBK's theory is that whilst the diameter of the spacer is made for the stock size throttle, the bore that it has, to allow for air speed up and circulation, makes the outer diameter (pre-bore) of the opening the same as the increased 73mm throttle...if that makes any sense.
