A ported stock TB would be a great addition to that setup.. I got mine from Thunder Racing... although some folks get their's done by Bauer: http://www.bauer-racing.com/throttlebodies.htm ..he powder coats them in various colors. :thumbs:
Talked to 2 people this week on installing larger throttle bodies. One is a outstanding field engineer forn GM and the other is a manufacturer of superchargers. Both told me the same thing. Without being ablt to modify the PCM computer, installing a larger throttle body only give a temprorary improvement because the MAss sensor input changes will be "re-adjusted and compensated by the PCM so the net return aftger compensation will be 0. One of them verified this on a dyno with a corvette. has anyone experienced this??
Crap! I just bought a 90mm TB and 85mm MAF. I haven't installed yet, but from what I am hearing that without additional tuning, I basically wasted my money. Is that right? I don't really know that much about the technical side of all this.
Every LS1 reacts differently to a new maf. I've heard many people having problems after changing the maf on LS1's. Do a search on LS1tech or LS1.com, there are many examples. Not worth it unless you are HIGHLY modified IMO. Spend your money on a p & p throttle body.
