TC Advice

[SallyCinnamon]

Sorry this has probably been covered before but not been on here for a while.I recently got my first TC mod & was looking forward to using up my normal coils ,getting some nickel & start using TC.Anyway i've done it but it's been a bit of a let down.I've varied my wattage/temperature but i don't seem to get the TH or even as much flavour.Maybe i was expecting too much but i actually preferred it before so i know it's a bit of an open ended question but is there anything obvious i could be doing wrong?Using Sigelei 75W,Crown tank & Uwell coils?TIA if anyones got any ideas
