I purchased a modified Dodge Charger a few months ago naively wanting the car young for college and got in at a deal i was pretty happy with at $16.6k, have been having some small issues i’m wondering if you all can confirm solutions for before it goes to a tuner next Wednesday. Car is a 5.7 with 98,000 miles and is a 2020.
modifications we think are done to the car:
-PCM unlock by hptuners and a tune i cant confirm who did it but i am pretty sure it is custom and was put on a dyno at one point
-long tube headers
-catless midpipes or straight pipe replacing cat
-rear resonator delete with keeping the factory mufflers
-aftermarket camshaft (car idle has a nice chop)
-JLT cold air intake
-Catch can
issues i have been having:
-raspy fuel almost sound in my exhaust
-sloppy throttle response sometimes but pulls hard others especially when flooring
- harsh downshifts and sloppy hesitant upshifts
could a better muffler and a better tune fix what i think this is missing? from what i’m reading this sounds like the most likely case scenario but
would like second opinions, my temperatures are all regular too.
