So I have a 2019 Challenger RT , Mods I've done so far is … Kooks Long tube headers , Kooks high flow cats , Air intake, Bigger throttle body , and straight piped exhaust. Obviously my CEL light has came on because of the highflows and I'm trying to decide what tune I should go with . So I need help/advice from you guys. I have been researching the MODIFIED PCM & TRINITY 2 COMBO. It looks like the best option for a hand held tuning device for my situation but it seems that you need to be emailed preloaded tunes from tuners that use your collected data from the tuner. Which would be more money onto the 1000$ this device costs. If anyone knows how much it is to get a emailed tune I would love to know . I need a tune that is for the headers. People also have told me to go with a dyno tune instead ,but there aren't to many places near me that do challenger tuning. So I need opinions on if a Dyno tune is better or the diablo would be fine. Idk I need some advice for what's the best option here before I spend all the money. Thank you!
