Runnin redtop in my s13 umm...walbro 255lph,stock injectors,blitz ecu, stock maf, z32 fuel filter. Car builds and holds bout 7-8 lbs. steady no boost leaks it just doesnt want to go from all i can figure is a must not be getting enough fuel pending checkin the pressure once i get the tools already decided to go ahead and get a nismo fpr thinkin that mine may not be working properly but if anybody knows anywhere else this problem could be im stuck if its not my fpr. INJECTORS NOT LEAKING O RINGS ARE FINE. NEW FUEL FILTER. PULLED VALVE COVER AND SET TIMING MANUALLY DEAD ON :tweak:

no im running stock boost at the time it just doesnt seem to wanna go...feels pretty good when u first start to roll into it but i mean at 75% to full throttle or so it just falls flat on its face doesnt wanna go fast at all nowhere near what it should be doing at least

still havent got to the timing yet there arent any boost leaks but i changed the fuel filter and some nice RUSTYBROWN fuel came out of it...the tank is nasty...this could very well be the problem gonna try and locate another cleaner tank and change the sock on my pump NO CLUE WHERE TO FIND A NEW SOCK FOR THE WALBRO IF ANY BODY KNOWS IT'D BE APPRECIATED. so changed the filter took it for a drive...still no power seems to have a miss now too
