Based on the majority opinion, throttle bodies don't do anything for n/a setups. The MAF is hit or miss with some people. The stock MAF flows enough for N/a applications but you can get gains from the way they are calibrated. I got my C&L because I was running 12:1 a/f and I was hoping that it would lean me out a little so I could get closer to the "optimum" 13:1 a/f.
If you do decide to buy one of those items, I would suggest trying to buy used from the aution block so that you won't spend a lot of $$ on them in case they don't work out like you planned.
Hope this helps.
