need some input. i have a fully built turbo charged ls/vtec. just finished putting it together. i have a s300 but it was giving me problems. with my 880cc injectors in when you start the car it idles fine, put your foot on the gas and it revs to 1500 rpm and makes a poofing noise then drops back down. long story short my s300 is being reprogrammed.
now i have my stock injectors in...stock map with check valves...stock ls ecu chipped for 9000 rpm. the car runs now...but when it gets hot it feels like it is not getting gas...keep your foot steady on the pedal and it will "leap frog" throughout the gears....i found out that if you keep pumping the gas pedal the car will get up to speed just fine...not pumping the gas pedal it will "leap frog" again.
now that you have heard my life story. what could be the cause of my problem. oh yeah forgot to mention that if you let it sit a day and crank it up it drives fine...till i guess it gets hot.
