Just as it says. I just installed a72mm TB on a jdm type-r pistons in a gsr bottom end w/ a P&P head and jun 3's. I put everything back together right it idles ok but when I press the gas it bogged out, does anyone have any info. that will help me out.thanks

 

did u try changing the fuel pressure?

 

u know what else i was thinking maybe your tps isn't signaling properly or something. If you woulda put that controller in you could do a sensor check

 

did you check your ignition timing?
