Has anyone gotten a bored out throttle body from this company, if so whats the quality and how much more performance does it add?, if any.

I've found a 100mm throttle body from TopSpeed, but i'm not paying $1000 for it.

 

i have a bored TB from them, great quality and design. i give them an A for product and service!!! as of gains, your not going to see much gains unless you increase the size of plenum and intake tube to match it. plus a tune!!!

 

I agree

They did mine aswell and it sure does look pretty

Jim at Proflow is very easy to deal with, i would do it all over again if i had to.
