Lost Power Can Anyone Help. Have 99 Vette. Changed To A Bbk Throttle Body, Kn Intake, Throttle Body By Pass, Over Size Mass Flow Air Sensor. Had A Band B Tri Flow Route 66. Car Moved. Changed Exhaust To The B And B Bullet with an x pipe. Now Lost Bottom End. Should I Have The Car Tuned?

"Oversized" MAF without tuning may have really
bent your airflow metering, even the "calibrated"
ones are questionable and the stock Delphi are a
misfit to the stock tune. Some of those other
mods are "voodoo" stuff too with little value and
some long-term downsides. The External Engine
section is the place to look for some comprehensive
mods "stickies". As a start though I'd remove the
MAF and replace w/ the stocker, and see what
that settles out to (give it a few days to recover
from mis-learning).

Try using your stock MAF to see if there is any substantial power gains. MAF's are extremly sensitve and sometimes going with a bigger or better flowing one can mess with your car.

Im with Raven.
I would have waited for the bigger MAF and TB until I was pushing some major air through them. Making those changes can actually make them flow "lazier" for a lack of better terms.....which is why you probably feel a loss on the bottom end

Guys, Thanks Alot Will take off the maf and put stock one back on and check. Is this because there is no back pressure with the new exhaust? had plenty of bottom end before changing it.
