Well ive been hearing alot of stories about 58mm tbs being very sensitive under low load where it makes the drivetrain load and unload itself causing it to jurk a bit. I have a Professional Products and i know a buddy that had a Lingenfelter tb with the same issues. Its VERY annoying and as much as i dont want to downsize to a 52mm Holley i bought to try out that has none of these issues and no loud whisting either i dont want to loose power as there was a huge big decrease in air volume when i stepped down.

The general consensus is that just about all of them require some minor tweaking. I had no problems with my Holley 52mm other than having to slot the TPS, but my 58mm (also a Holley) needed the same and additionally some PCM work to keep the TPS from going too far past WOT.

im running a bbk 58mm, bought it with the motor. doesnt have a problem with the tps. it used to stick closed after a hard run but it hasnt done that in a long time. the linkage had some play in it. a quick spot weld fixed that. (play between the cam and the blades) other than that, drives great

Yeh the 52mm holley i have had zero issues it was top notch and didnt drastically drop the rpms down to the 4-500rpm area and bounce back up 750ish when i popped it out of gear coming to a stop. I know the BBKs are noisy generally and have issues with idle sometimes. I think if anything id probubly grab another Holley as i hear nothing but great things and they look plain awesome. AS&M and TPIS are nice too but just alot of cash and dont find them up for sale used alot.
Thanks!
Thanks!

I have a Holley 52mm. I did slot the TPS to make sure it was spot on with the readings, although I am sure it would have been fine for 99% of the people out there. Other than that it has been a quality piece.
