Since we're all talking about how to tune, here is a great link that I always keep saved. Has "in depth" reading as well as a quick guide.

I'm running factory setup with soft aka 4 rib fronts and super soft jc handlebar v2 rears, aka red foam all around and I don't have any twitch or push. I know a lot of guys like to run the front tires with tread but I find that any time I do, I push a lot in the corner.

I have these pistons from day 1. Buddies at the track are running this shock set up.

Shorty all the way forward? Wow. You must be running on some high bite stuff if you don't need any weight in the rear?

My initial recommendations are check your toe in the front. Toe out with often times make the front feel twitchy. I like to set it close to zero erring more towards a touch of toe in. Try lowering the roll center by adding 1 or 2mm shims under the ball studs on the camber block in front. This should calm down initial turn in and give you better mid corner traction. These are generalizations. More info would be required to really help dial it in...
Hard turn in - is that initially or mid-turn off power? Is the push only when you apply power? Does the car feel twitchy in the front when not in the turns? What kind of surface/traction are you running on? Are the turns at the track smooth or bumpy? What position are you running on the front trailing axles? How much camber and toe are you running? Is that oil weight 27.5 in front or rear? What limiters are you running in the shocks? How tight/loose is your diff? How much toe/anti-squat are you running?
There are so many variables that must be considered. Lately in my testing I have found that changes in the rear of the car make as much difference in the front as in the back. Finding that balance can be tricky.

Can anyone point me to where a front shock tower would be in stock at?

I am not familiar with Losi 55 pistons, but check your oil. Are you saying 27.5 front 32.5 rear? if so I would swap those weights around at least. It seems to me that people are running thicker oil in the B5 compared to the 4.2. I used to run 30 front 27.5 rear, now my B5 likes 35/32.5. If you meant 32.5 front, 27.5 rear, I would try increasing the weight in the rear.

Ya always thicker oil up front. It was even worse with the 35/32.5.

The hard turn is Initial. When I apply power and try to be "fast" through the corner it just pushes wide. It may just me trying to drive it like a mid motor cause that's all I've been running as of late. I'm running a fairly smooth high bite clay track. Corners are smooth. 3mm trailing. -1 camber all around with no toe. 27.5 rear 32.5 front. Medium set diff. 2.5+2 toe block. 23mm ride height front and rear. B4.2 jcon wing with wing mount flipped so it's at a angle with screw hole in rear. Same tires as everyone else with success. White spring rear green spring front. 17.5 reedy 33/72. All stock locations on ball studs. Think that's enough info lol thanks for the help.

A few things to try. 2mm trailing , 21g of weight in front of servo , black springs up front and I run 4mm of limiters in front and 2 in rear.

Seems everyone is going to 1.6 rear pistons right away. Inner rear ballstud washers seem to be popular at 0 or 1mm. 35 front oil seems to be popular as well, and 30 out back. Seems most everyone on any med to high bite tracks having success is running the exact same front end setup, although 3-hole 1.4mm pistons up front seem to be around.
I saw that setup but Im not running that reedy sq pack. I would think running a shorty I would need a slightly different setup
