I understand there are two basic units, BBK 80mm and the GM throttle body. The GM unit is listed as 97-01 which poses a problem for me as the intakes are two sizes with the 01 being larger than previous intake openings. I am seriously considering making this move to inprove peformance. Which is the better unit and what are your thoughts? Would there be much advantage to another MAF Thanx Rad :confused: :yesnod:
FWIW..I had Agostino Racing Engines port and polish my stock TB when I did the heads and cam..opened up the TB and I pulled the screen on the stock MAF..Good for maybe 8-10 RWHP..with mods..Just my .02 :D
Another option is one from TPIS, it flows over 1000cfm
It will be avalible in a month or so.
"vetetech" sent me a fax on it, but my wife cleaned my desk and now I can't find it. It's not listed on the web site yet.
But the flier clames a 22hp insrease on on mostly stock engines. ($695 I think)
Also it requires a LS6 intake that they have to modify to reach those numbers. (exchange $495)
They will sell an adapter instead but you loose about half the hp gain.
Thanx for the info. Do you have a link to contact TPIS to gain info re: the vetetech TB. I think my current intake is an LS6 as it has a larger intake port then 97-00 LS1 intakes. :cheers:
Just installed a Shaner S2 and all I can say is that you can feel the difference(better throttle response). The S2 looks like a piece of jewelry when you see it. Only when you lay it side/side with the stock unit, can you appreciate the work Mark does. Give it a look, you can do a lot worse for the $169. you'll spend for the S2.

PS...not downing the other TBs available, just sharing my experience with the S2 unit.

Since you have an '01 you already have a larger MAF than a '97-'00. A lot of places don't bother to sell MAF's for '01-up because there isn't much if anything to be gained.
You guys just supplied me with the answer I waited for. As I am in supplier-evaluation for a ported T-B, I wrote two times (!!) to KATECH for inquiry - never have received any reply. No flames intended, but may be those guys are too noble to listen to prospective Customers (?). Who knows......sorry.
So, now I target to get one of those Shaners modified T-Bs to install (I have already the ZO6 Intake Manifold to my full satisfaction). Now, could one of you Shaner-Customers pls report about the return time ? I tend to send them my own Throttle-Body in to have it CNC-worked and polished.
