Okay I am new to this forum.. Just purchased a Black Charger R/T, added the Mopar cold air intake and the Mopar (Borla) hi-performance exhaust. Did a few cosmetic add ons such as the Daytona R/T Mopar OEM Spoiler and the Daytona R/T emblem on my grill, and Shogun Z1 chrome wheels. Here's the problem, I purchased a stage I Jet performance chip and I don't feel any difference. (neither low end or top end) I do however see my MPG go from 17 in the city to around 9 MGP. There are no problems with the chip, it is seated correctly. I just wanted to see if anyone else out there has wasted $300 bucks like me or am I expecting too much??
