[QUOTE="PutraEvo, post: 1685076, member: 12639"] today mechanic said that it is because of the fuel...cos once engages at 3rd to 4th gear, there is pop pop sound at the muffler during which RPM was 5k. thats why speed cant go up eventhough RPM at 5k and boost was around 1 bar. I donno whether is it true. He said it is not clutch slip cos at the 1st to 3rd gear,from RPM 1k to 4k or sometimes 5k...speed can go up smoothly,only at RPM 5k or 6k...speed not goin up...the sound just like idling at high RPM. if really because of the fuel, really need to change the fuel pump or add one more fuel pump? cos i know original EVO II has two fuel pumps,correct? i have fuel regulator also plugged in. Thanks! [/QUOTE]
