hey just curious, i have a stage 3 too, and have never raced mine...but i have talked to ALOT of other stage 3 NA's that say they run mid to high 14's...so i think you could run faster than 15.2 for that many mods..you could be able to break the 15's, a STOCK 90 NA, runs it in 15.4 at 91mph.... source from [ http://www.z32.org/html/z32perf.shtml...read ] the results...
