hello everyone

i have a qusetion about my tune,

@1700-2000 rpm @the 400-500mbar column i fell a slight stumble, ut feels like the engine is reving up and down about 100 rpm's (like a limp mode)
(afr's are good)

im runing a stock p28 ign map
ngk bkr7's 0.28-29
all oem ignition components


thanks
