i have a ls vtec and it redlines at 6500rpm.
my setup is

8:5:1 srp rods
tunertoys h beam rods
b16a3 head
gsr timing belt/ waterpump
p73 ecu(jdm b18c1)

the timing belt is all aligned on the car but when taking a timing light to it the shows that the timing is off a tooth or 2.... runs fine jus need help

there is no knock sensor or nething but i do not believe that would cause such a drastic problem.. need help!!!!!!!!!!!!!!!! plzzzzzzzzzzzzzzz...
 
it could be because of that timing! when mine did that i couldn't get vtec it would hit like a rev limiter i checked my timing and it was off by two teeth fixed it and it was fine! try that first
