Need larger Injectors for???
Hot Cam Kit, Exotic Muscle long tubes and now I thinking of boring my TB to 52mm.
Will the stock injectors keep up, with the right programming??
Thanks :seeya

I would try to use your stock injectors with either more fuel pressure or program change till they run out of capacity.
It's better to stray on the small side than to have injectors too large and cut pressure or run too shout on duty cycle (similar to running over 80%).
Though if you do a cam & headers you may be getting close to their limits.

I believe you will be fine. A little more pressure will make the injectors perform as larger than they are.
Formula for pressure effect on inj size = sqrt(new pressure/old pressure)*rated size
Example: new pressure 50psi old pressure 43psi(stock) rated size 22#
sqrt(50psi/43psi)*22# => 23.7# Which for us put us into the low11 and high 10s on 406 motors. So i think you have more than enough injectors even at 46psi. :yesnod:
