I think you went too large out the gate is all. If I am purchasing a cam for something that is daily driver, The V220 is the largest I would go. It will drive nicer than the 225 as it works much better with the stock converter and has around 0 degrees of overlap. Don't assume all cams drive the same. Once you get around 225 degrees on the intake lobe with a 114 or tighter LSA, you are now dealing with positive overlap and a cam that wants a 800rpm idle. The V225 has at minimum +6.5 degrees of overlap and could be more since I don't know the exact spec on the exhaust lobe( used 240). That isn't ideal for the stock converter in automatics. Then you need to ideally raise compression to get some of the tip in low rpm throttle response back.
Moral of the story when cam shopping for a daily is that you want to keep overlap around 0 or slightly negative... it should drive 95% like stock with proper tuning and work great with stock converters. Positive overlap trades bottom end for more peak power. You start to lose low end and have to compensate in other areas...gears, larger stall, more compression etc.

Appreciated man. Last one, my tuner is recommending the following custom Cam Motion 219/233 118 LSA, How will the drivability be (i.e. will it surge/buck at low speeds) or will be similar to the stock cam? My car is a manual and im really hating the v225 at low speeds it surges like crazy in 1st and 2nd at low speeds below 1500rpms.
