For what it's worth, here's my input for you.
You say that the car is pushing at the end of the straight. I'll assume for now that this is still on-power - i.e. a sweeper corner.
You don't mention if the car is rear or mid engine - but again, I'll assume mid based on the fact that you are running yellow mini-pins which would suggest to me a typical UK/European High Bite indoor carpet setup.
I'll also assume that you've built the car according to the kit instructions. in terms of ball stud positions and washers.
OK - now my 0.02 worth.
1) the kit instruction setup favours a rear motor car. If you are running mid-motor then you'll find the roll centres are not optimised. You'll find good setups on tlracing.com - look for anything with a midcar setup. You'll find that the front roll centre in particular is very different for the rear car than the mid car.
2) The kit front spring is very soft. Running a harder spring (either Green or Blue for the mid car) will enable the car to react more against the steering input - thus making the car feel as if it is gripping more (so long as the surface has grip)
3)You can encourage more weight shift forward during the turn by running the tapered wedge in the front kickup - the flat wedge will resist weight shift which makes the car feel more consistent.
4) Reducing caster by using the optional 5 deg or 3 deg blocks will make the corner entry feel sharper.
5) Good tip on the servo throw from cryer-evo -the 22 is very sensitive to the servo horn placement and just 1 spline out can result in not enough lock one way.
6) Increasing anti squat at the back will help the car to rotate in the turn - although this is maybe more noticeable in the hairpin type corners.
7) You could reduce rear toe in - go from the LRC 4 deg to a 3 or 3.5 deg block will help
8) going from Low Roll Centre to High Roll Centre will make the rear of the car feel looser. This is not always for the feint hearted though
. I prefer the High Roll Centre blocks but many racers want the rear of the car to feel more locked in and they prefer the LRC. If you do change to HRC, you will need to change the antisquat shims and inserts to the HRC shim set in order to keep the same antisquat angles.
9) Going longer on the rear wheelbase by shimming the rear hubs backwards will also increase steering feel on corner entry.
Hope this helps to start with. The best bit of advice I can suggest is that you take a look at the setup sheets from the team and adjust your own setup one step at a time - that way, you'll appreciate what each change is doing for you and you'll hone your own setup from there.
But from what you describe, it sounds to me that you are searching for more on power steering and/or increased corner entry. I'd look at the roll centres and inner / outer pivot heights to begin with.
