How do you know to replace injectors?

[markgb]

Hi all,

I have been trying to get the Cupra over the 200bhp mark.
She's been remapped by JBS on a generic stage 1, got a CDA induction kit and a Baileys Diverter Valve.

She's done around 91k, and I'm thinking to basically give her a full service.
Plugs, coil packs, oil, but I'm also thinking about the injectors.
Are the LCR's the same, and would replacing them help my get over the 200bhp?

Cheers.

what power is car running at moment? have you had it on the rollers?

I'd of thought it would be at 200bhp with the mods you've listed.

I take it you have a Cupra petrol rather than TDi?

If so, judging by your avatar it looks like you have a facelift model with K03s? If that's true, you should have made approx 210bhp on a Stage 1 and should be looking for fault codes and boost leaks. Injectors aren't often changed and I haven't heard of an LCR owner doing these unless going big turbo. If you have a K03 car but with facelift kit, then your next step is Stage 2 or swapping your K03 for a K03s.

she's been on 2 different Rollers.
When she was firsted remapped, she made 196.6bhp (on a hot day)
She was on Monsters rollers last month, and only made around 190bhp (although most there were around 20% down).

As far as I know, she's got the K03s.
When the funds allow, I'm going for a hybrid K04s with manifold and exhaust.
Just want nearer to 210bhp in the meanwhile.
