Hi, i have just fitted a fmic to my gtst and it has developed a really bad flat spot between 6100 rpm and 6700 rpm, its still running stock boost and only has a hks filter and full exhaust system, still ran a 14.281 @ 98.5 qtr at USC last weekend even with the flat spot, anyway any ideas on the flat spot??? many thanks Paul:dunno:

let me guess..... You havent done a search :slap:

This has been covered bazillions of times.....
Your getting all that extra air but you have no fueling mods...... Sort your fueling issues with a safc or some other piggy back ecu or join the group buy for the power fc... If its not gone after that which it should off, change your coilpacks to splitfires, not gone after that, change your afm
