I can understand that hot or cold temperature can affect the performance (power) but the engine should still be smooth at least. The engine feels different on a cold day in the same week with the same gas in the tank. Do you think Delicious tune can help? If I order Flash & Go tune, do I need to replace the MAP sensor?

I originally had a C30 with everything else stock on the CARB tune. Jackson’s CARB tune is one of the the better ones out there but it is still tailored towards emissions. My biggest issue was the engine just felt sluggish below 3K RPM like slower than stock. It didn’t matter if it was warm or cold out. A tune completely fixed this along with picking up about 20 whp. I don’t think you should need a MAP sensor unless you’re increasing boost or something is wrong with your current one.
