I think that I might be a little above that however I am trying to move a Z-71 crew cab.
i just recently switched intake manifolds. had stock manilfod, ported throttle body, it was 75mm. I ordered a 2010 silverado intake complete, with fuel rails, injectors, which i do belive are bigger. it came with 90mm throttle body, 4 bolt style. it was brand new never bolted to a motor, came with all new bolts also. after the tune, tuner said that he had to add alot of fuel at WOT, i could deffinetly tell a differnce in power and throttle repsonse. intake looks ugly still, i would rather had a ls2 intake, but it works and im happy with it. also youll need a X-link adapter which runs a lil over $200
I had upgraded my injectors to the 31 lb with the last tune. Had the trans beefed up and added a small stall. It should be ready today around lunch. Planning to go to the track tonite to see where I am now as far as ET and mph in the 1/4. Still plan to try the 90mm setup on my 5.3. Later on, might switch to a 6.0 but for now i'm sticking with the 5.3. What does the x-link adapter do and where is it installed?
well the plugs are different from a 78mm tb to a 90 tb...one is a 6 pin and the other is a 8 pin...the harness adapts the stock 78 tb harness to the 90mm harness so it basically just makes it a plug n play type deal...minus a couple small adjustments in the tuneQuote:

My truck being a 2001 with DBW however didn't need the xlink. I just spliced on the correct plug for the 90mm TB. The 2 extra wires are redundant 5v+ and low reference, the new TB doesn't need them. I did my intake swap last night. Throttle is working perfectly, now I need to do some tuning, it is idling like crap.
Lol yeah i didnt wanna get to technical on it so i just keep it easy...:chevy:Quote:
