Kaylee and Jonathan drove in from Texas for the Blue Belt Performance Package. The mods included Green high performance air filters, Gigs ported throttle body, Brisk silver racing spark plugs and Tapout resonated downpipes. Plus we also included one of our carbon fiber engine covers. Baseline pull was 426 whp. JB4 Map 0 put down 449 whp. Map 1 made 503 whp on 93-octane. Then we created a custom map for 100-octane that made 551 peak whp. Jonathan and Kaylee will certainly be arguing about whose turn it is to drive on their 1,003 mile drive back home!
