3ur-fe limiters

Hi every one, trying to tune lexus lx570 with 3urfe.
i have dyno and stock was 250whp and 0-100 km accelaraition was 8,6 sec
after tune on dyno i get numbers 270whp and improve accelaration for 7,5 sec
max speed was with stock 217 and with tune still 217kmh. in ecu i found limiter 220kmh, moved it to 250kmh but car goes only 217
than i ordered long tube headers and installed it. on dyno i get 310whp
but accelaration is still 7.5-7.6 and max speed still 217 LOL
i thought may be its sofware problem and found HP tuners
yesturday ive tried with HP tuner, no way, still 217 :banghead:

i dont understand, how 60whp gains doesnt affect on top speed

Can you post the tune, or at least the stock tune?

sure that is stock file

From what's I can see in the log and the tune, the wall you're up against does not appear to be the ECU holding you back. Throttle is not being closed.
