I just recently installed my ls/v and had a reputable tuner do my ecu. Well to make it short. My car won't rev past 5500. Its like hitting revlimt but vtec engages at 4800 fine till 5500. But when sitting still the car will rev to 8k just fine. So if u guys have any advice please lmk. I was thinkn the dizzy but why would it do it only when driving

 

any advice people, i was told a couple things to check. timing is dead on, dizzy is an obd2a dizzy with ear cut off to fit which ive done numerous times.i was told to try a vtec dizzy or vtec solenoid

 

Try a different ecu sound like thats your prob.

 

i did still nothing, i used stock p28, i installed my chip in my budyys personal tuning/datalogging ecu and did the same. it only does it while under load. i was told to try dizzy
