I just finished my ls vtec setup fired up find and idles ok not great but ok. the problem is i can open the throttle very slowly and it revs up fine but if i open it fast as if i just laid my foot on the gas it just bogs down. i talked to a friend and said this could be a combination of my IAT not working (it melted in my old motor ) and my ignition timing could be off. anyone ever had this problem?

 

What are you using for management on the car?

 

just a skunk2 chipped obd1 gsr ecu with a obd2b to obd1 harness havnt wired vtec yet but that should cause a problem. i dont think
