MONGOOSE 800+ PERFORMANCE PACKAGEBoost your Trackhawk to 760-820whp (depending on dyno) with our exclusive MONGOOSE by Barth Tuning package, utilizing our MONGOOSE 2.78' pulley and hub assembly, all on 93 octane!As one of the originators of Modern Mopar. Car will hit the rollers again next week. Tuner said not enough spark so we changed out the plugs.
I’m wondering though that last time on the dyno we couldn’t get the car to go past 6100-6200rpm.
So far so good no codes no tuning issues.
