Decapped injectors

Been looking for red 740cc injectors for my95 wrx import but can’t find any,I’ve been offered yellow decapped injectors which are apparently 800cc, would it be better buying original red 740cc or decapped 800cc yellow injectors, Car was on a dyno last week and only produced 286bhp with mods,mapper said get red 740’s as I’m looking to gain 340ish, so going to change Injectors and map sensor. Never come a cross decap injectors before.

any help appreciated.

Yellow 440cc injectors will get close to 340.

edit:

550cc are good for nearly 400BHP why would you need bigger?

Yes that’s what I thought as only want 340ish, when I bought the car last owner gave me a printout of 301bhp,but when I took it back to tuner as had an issue with car he put it on dyno It only pushed 286bhp,He said get 740cc red injectors and 3 bar map sensor and that will take it to 340.

De capped 440's changes the spray pattern,, Been down this route.

440's as said can achieve mid 350's aided with a fpr.

Thanks to all the replies guys appreciate your advice, spoke to Mapoer yday he said he only advised bigger injectors just in case I wanted more power later on,told him 340 is all I need as don’t want to put too much pressure on standard gearbox,so he now said get yellow 440’s that will see me 320-330 at a push,still low to be honest, I’m stuck with one mapper as I have an Alcatek ecu and this this mapper is the only one who can access it.

If I were to get yellow 440’s,3 bar map sensor and fpr should I be seeing more than 320bhp,
