dunno if this is the best place to post this question
just wanted to know i have a r33 gtr just got it tuned recently with a standard apexi power fc and hand controller and it seems to jolt sometimes just when driving it normally. i have it for like 2 days and it has jolted like 6 times not when stress or anything like that just when normal driving. apparently this is normal cause there is some software problem with them . i spoke to my mechanic he said its normal.. i think i might call him agian normal cause it keeps doing it and its frustraiting i dunno is this normal. if you could help much appreciated if not sorry for waisting your time
