Hey everyone. I'm new to the forum and I wanted to ask some other owners if they have experienced something similiar.

Over the last few days my 2018 TH has been feeling sluggish. I couldn't break 4.0 on a 0-60 and I typically do a 3.4-3.7 on a daily basis.

So I turned on the gauges in the middle console so I could watch HP and Boost. so I did a few 0-60's yesterday and the max my HP would get to was 599 and it couldnt leave the 10's on boost. this was resulting in 0-60's at or above 4.0. This was in street mode, which I normally am. It was about 103 here in dallas and humidity was ridiculous at like 60-70%.

Everything seems to be running normal, tires are in good shape, normal tire pressure etc. I always put 93 octane in. I'm not sure which of these things matter. Any help would or ideas be appreciated.

Heat soak? Look for my thread about the interchiler. this might be what you need. I wouldnt doubt it but saying that there no way anyone will know the anwser with out way more info. but a solid guess is heat soak.

There's your answer.....


It's summer time in Texas. My 0-60 times are off by 3 to 4 tenths too. My SRT's before the TH were off about the same (%) amount during the summer months. Even my Vettes were slower in the summer, although maybe not as much as the hemi's.

Once air temps get above 60, I don't even look at the performance pages anymore.
