hi guys i got my ae86 tuned today again. only problem is at it makes good power till it hits 5500 6000rpm then goes flat looses 10hp then slowly picks back up and makes more power at 7500 on wards. then we decided to turn off vvt via the haltec and it was a nice solid curve to 127hp except it was about 20hp under the line of the vvt run. this said it makes alot beeter mid range power with vvt then without, i just have a dead spot at six. dose any one know what this might be???? i got told it maybe i need longer trumpets as mine are very short????
