    Does my car have a tune ?

    Ok stupid question but I bought my car used and know this about it . It has some kind of aftermarket cam (hits a good lick at idle) has long tube headers , off road y pipe , a small converter i can footbreak about 2500 , a 3in bullet muffler with a turn down . Car runs decent but just when it really starts to pull it will hit the rev limiter (about 6600) every light in the dash is on but there is zero torque management and will jar your teeth on the 1-2 shift . So im sure its had some kind of tuning but why not turn off the lights and bump the rev limiter ? Any way I can figure out what has been done to it ? I'm assuming it has stock heads and intake since I can see they have blocked off the egr. Thanks for any advice 🙏

    To be honest without hooking up HPTuners or Holly EFILive you will never know.

    Sounds like it.

    Ok thank you. I kinda figured it may be something like that . I would just send it out to be returned but have no clue about what cam is in it. Not gonna be pulling the motor apart till maybe next year. Thanks for the reply 👍
