Under normal running conditions the computer will correct the fuel mixture for the best possible mixture (emission). However by adding resistance to sensors at full throttle the mixture will be richer & the ignition system will allow a bit (2-3deg) more timing. The 87 & later cars use a computer for timing & there ins't any way to change timing other than resistor changes.
We're talking minor changes 3-4hp max.
