Hey Spunkster I was able to fix the idle issue, but the next issue is the car goes on limp mode when it crosses into vtec. Unsure what to do.

just put on an rbc intake and loaded up the hondata calibration file for CAI, RBC manifold, CAT delete, Catback Exhaust, Idle started surging from 1k-2.5k rpm. unsure what to do please lmk!

- K-Tuned SRI 3.5 (to headlight)
- RBC intake manifold
- Stock injectors (310)
- 2.75 in DP
-2.75 in invidia ...

I'm pretty new to Hondata I'm unsure how to tune the car.

I currently have a k&n typhoon sri, 2.75 in dp, and a invidia n1 3 in exhaust. I was wondering if it is running safely. Pls let me know thank you.
