Does anybody know of a company or programer that i can buy that will upgrade my stock computer. my friend has one in his rsx that makes the vtech kick in at around 5k rpm. i was just wondering about the whole computer in general tho. thakns

 

entry level: VAFC (300-400 with harness)
advanced level: AEM EMS (1200-1800)

they do not include dyno tuning.

And while yes, you can lower the vtec in the car, it isn't that optimal to lower it by more than a hundred or two.
