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:
