Default hemi feeln sluggish

It seems that the hemi is feeling sluggish lately..As for mods I have a flowmaster cat back,volant intake and predator tuner,I also just recently installed the jet 180 thermo..From what i understand I cant run a catch can ,I have a 08 ram and I cant change the fan setting in my ram,I dont have the option on my predator and from what i understand i dont have a fan that i can change??? Im running the 91 tune in the predator and using 93 octane gas,would i be better with the stock thermo,the truck felt pepper with it,and with the enclosed pvc system a catch can isnt an option..wanted to change the plugs for i have 37 k on them but will wait first to see if there might b another issue first..........

would running different oil have an effect..I think 5-30 was used instead of 5-20..the oil was changed right before i noticed this

Has the tempature outside gone up lateley since you've noticed this? Cooler temps can make it feel slower.

that's interesting because our motors should be more responsive in colder weather (that why most will try and hit the tracks during winter)...now, a 180 tstat and colder weather, the fuel prolly needs to be leaned out a little bit..

My bad I was busy at work and got it wrong. Colder temps are good for engines and hotter are bad.
