I'd get a baseline before an install though too bud. Will it need tuning? Pics and measurements would be cool too lol just saying.

Keep us posted bud!! BBK throttle body's are good stuff! I've had one on my C1500 for about 4 or 5 yrs! Never run so good until I put it on ! Thanks!

My BBK Throttle Body worked a lot better than my OEM did! IMHO you can't go wrong with a BBK Throttle Body!

Every advertisement i've seen of it says it doesn't need tuning. Now that it's FINALLY coming out, we'll see.

Plug and play AFTER you switch everything over. It doesn't come with all the electronics. You have to move yours over.

When you install it, please check the size of the TB opening vs the intake manifold opening. I haven't had mine off to see if the IM opening is bigger than the TB. If they are the same size, a bigger TB shouldn't do much.

Has anybody been able to get a bbk throttle body. I ordered one through wild vettes, then cancelled the order after 45 days with no timeline for a delivery. Ordered a vmaxx should get it in a few weeks.

Well I just went thru two 95mm bbk throttle body's. First one made my car ideal real low at start up and when my clutch is in. Also at road speed it had a surge. Called and they sent me a new one. Same thing!! Went and had the low ideal tuned up but still had a surge at road speed. Could definitely tell a difference in throttle response on the road and at the track. Did I pick up at track? Nope. Started surging real bad after 3rd pass. Oh yeah and I did replace the mass air flow sensor after the first one. Anyone have any suggestions on what I can do to fix the surging problem? Would love to put it back on the car. But can't daily drive with that surging.

sometimes...sometimes you need to relearn your computer this has happened to me after cleaning one let along changing sizes...in fact i am super surprised that this doesn't happen more often based on how our GEN4/E-38 PCM works

check this thread out i was scratching my head for over a week after cleaning one and i had all the same symptoms as you did...i used the scanner/relearn feature on my HPTuners scanner to fix it but i believe Snap-On's Modis will do it if not the dealer. there is also a DIY thread on how to relearn your TB manually yet in the below thread you can see that even method that does not require a scan tool is a fail from time to time

If you look in the other BBK TB thread, you'll notice that there's a lip that is highly suspicious for causing tuning issues. It could easily cause surging as well. If you're the handy type, you might consider porting the intake mouth to match the TB.

The relearn process is very easy and takes only a short time to complete... It's also the exact same issue that others have after installing a new identical oem part or from cleaning the tb if it were my money and or my time and labor I would try the easiest option first

If u just tune it out then all you've done is butcher a perfectly good tune

Already had it tuned for the 95mm. Fixed the ideal problem but the surging was a mystery. I ran it on the street with the new mass air flow for about a week and then made 3 passes at the track. 1st pass it started surging bad after pass. 2nd pass same thing. 3rd pass started bogging a little at green. Start!!! Went home put the stock one back on and bam no surging. Just idealing high. Went back next day and put my previous tune back on. Now car runs fine. Just wish it would of worked like it said it would.

I spoke with a very well respected tuner in the LS community and he explained some issues with tuning aftermarket throttle bodies.

The problem with so many aftermarket throttle bodies are how they work the first 10 degrees of rotation. The good ones are scooped so a degree or two of increment changes the airflow by small amounts. Idle recovery is smooth. Most aftermarket TBs are hogged out for maximum airflow and a one degree change in rotation allows 2-3 times the amount of airflow correction. The throttle winds up over correcting and overshooting the idle. Some of this can be tuned out, but most of trouble is caused by a poor design and no amount of tuning can fix a bad design.

Is that not what the Vmax and other ported throttle bodies do? Remove the "scoop"? With those like the BBK 95mm maybe it is a little worse do to the larger diameter. Then what does that say for the 102mm versions? Seems like they would be even worse.

Well I looked at the video Demon 1LE and sure enough it was binding a little. So I sanded the blade a little to stop the binding. Put it back on one more time. Started the car and it idealed a little low. Gonna drive all week to see if the surging stops now that it's not binding. Not gonna mess with the tune like bbk says. Bolt on a go!!! Will post back soon.

Update!!! Fix the sticking plate. Got a strong maf. New vacuum hose. Tried tuning again. And the verdict is- Same thing!!! My car don't like it. Surging at normal driving speeds. Idle is low. After a few passes at track car floods a little. Did not pick up any at track. Maybe it's just my set up? Cam only? Gonna let my buddy put it on his stock SS any see if he has any issues with it. Man what a mystery this thing is!!! I got other bbk stuff on my car. No problems at all. Wish this would of worked. Car runs so much better with stock throttle body now. Will post back after my buddy runs it on his stock SS for a few.
