Can really use some help

[Alvin48185]

Hope someone can help me figure out what’s going on with my car. It’s a 2015 gt with the performance package. It’s stock beside a jlt cold air intake with a tune for the intake. The car has 25,000 miles on it. The other day while leaving work the car had a weird feel to it. When I took off it felt like I lost most of my torque. The car shifts fine and revs fine but just doesn’t have the power behind it. The clutch also is engaging late. I have no bad smells or any slip in the clutch. Shifting gears are fine. I don’t know what could be causing it. I have tried to look online and I can’t find anyone with this problem. Help advise would be great.

Did you get gas with the octane below 87? Use good octane boost, add 91 octane to the tank. Check fowled parts.

I second Charles on that. Add octane booster to gas and fresh fuel. Did you recently buy gas from arco? I assume the tune has been there for awhile and from a reputable shop, otherwise switching back could be a good idea, just to compare.

I use 93 octane. I thought the gas could be an issue I only had less of a quarter of a tank and went and filled up same issue. I can’t go back to the stock tune since the cold air requires a tune. I have had that tune for about 3 years.

This is a wild guess, but have you checked for fowling or blockage in the cold air? I'd follow combustion/exhaust. If it was tranny you'd feel that. Right?

when is the last time you cleaned the MAF ?? If it's really dirty, it could be causing just that problem
