this is correct. if you run a dry kit generally you'll have some sort of control over the ECU to tune for the nitrous delivery (both the extra fuel needed and it's generally good to retard the timing a bit as well). dry kits can be tuned a bit more precisely than a wet kit, but again you have to have some sort of ECU control to really take advantage of it. wet kits are far more plug and play to get it working right.
