as far a HP, it really doesnt make much, just allows you to burn all the fuel that you ingest. it defintly inproved my throttle response, last sat. i had 3 redlights a .418,.458, and a .439 in the second round, which sux. i used TAYLOR wire condu. to cover the harness. i centered the box on the strut tower brace and drilled 2 5/16" holes clean through and bolted it fast. i had no other place to mount it under the hood unless i mounted it to the battery, lol. i ran the power wire to the back of the alt to give it the shortest distance and grounded it to the pcv plate bolt. i got the DIS 4HO box , which they dont recommend to run on the street, its a race app only, so they say. the kit includes a jumper plug that you unplug the harness from the box pigtail and install the jumper in the harness. this will take you back to the OEM ingition system.
also on the strut brace i have this written on it
" ONLY PUNKS DRAG IT TO THE STREET"
