ok so i have a turbo b16 and around 6000 rpms it pretty much looses power alot like wont go past 6000 its tuned on crome i believe and i rebult the bottom end because the compression ratios were badddd so it that the reason i need a retune is because the compression numbers are different and way higher or what do you guys think could be the problem? also im not sure if vtec is actually working is there any way to check to see if vtec works or not i cant here it crossover or anything and also heard that could be while im loosing power at 6000 or im leaning out in a/f any help would be appreciated thx

 

if your falling flat at 6000 that would lead me to believe there might be an issue with vtec

 

i believe im just running lean i wired up a vtec light to see if its actually working and ya at 5500 exactly vtec works but still falls at 6000rpms im gonna get it retuned and see what happens then

 

how did you wire up a vtec light? pm me bout it
