i have recently purchased a 3000 gt turbo r4 and i tuned it up to a turbo 3 stage and it was fine. Then i saved up and got stage 4 turbo. now when i get up to gear 6 it only gets up to 263 and then drops down to 250 and repeats itself. this is with a racing transmission and a triple plate clutch with a racing muffler. i have tried switching the clutch to normal and twin plate and i have tried switching the muffler to semi racing. i tried switching the transmission to normal and it went up to 350 and dropped down to 330 and repeats . i don't know what to do. can someone please help me out.![Confused :confused: :confused:](/wp-content/themes/gtp16/images/smilies/confused.svg)
