I just installed the cams and have yet to tune them but I'm wondering if I need to upgrade my injectors

I have RC 270cc injectors AEM Fuel Rail and SX Fuel Pressure Regulator which were enough for my CTR cams.

Without tuning, the power of the stage 2s at lower rpm feels a lot weaker than the ctr cams. Is it normal?

 

what was your duty cycle and FP tuned for your last setup?

more generally, what whp did you put down?

It was tuned by my previous owner and I didn't dyno the car with the ctr cams..

Here's the engine setup (Mind me but I just copy and pasted the list he gave me, some of them may not affect the performance I know =P, too lazy to delete those).

I would say the whp would be about 170-180 with this setup

* 11.4:1 Compression Ratio
* Two Layer Head Gasket

* MSD Distributor Cap
* Magnecor Ignition Wires
* NGK Iridium Spark Plugs
* Cusco Oil Catch Can
* Dual Core Raditor
* AEM Fuel Rail
* SX Fuel Pressure Regulator
* B&M Fuel Pressure Gauge
* AN-R Single Stage Intake Manifold with ported 66mm throttle body opening
* Integra Type R Throttle Cable and bracket
