heres my setup:gsr i/e/h vafc tuned to 159whp and 118 ft lbs tourque. problem: car leans out in at 5800-6000 rpm right after vtec kicks in. ran a 15.4 best time with a 2.4 60ft. weighed in at 2620 with myself in it. wen i got home the spark plugs were gapped a little high about .52 with ngk 11.

 

sorry to say thats some horrible #s for stock gsr you should at least make 120 range in tq and hp is there but there is definitley something wrong. you may need to help me a little more in your setup i dont know what you are using product wize then i can help you looks like to are running to much air and loosing velocity in your setup and thats why you arent making tq #s like you should
