[QUOTE="HLN A55, post: 18736, member: 46"] Hey guys... interesting thing has happened the last few times I've taken the car on the highway. Maybe this issue has always been there but just noticed because I hadn't driven the car so often on the highway before??? After about an hour on the highway at cruising speeds this is what happens... If I apply 1/4 throttle while still in 6th (about 2100rpm or ~120k) the car stumbles... kind feels like its choking. No error codes or notifications. If I down shift to 5th... all ok. If I'm going faster in 6th... say 2400rpm or ~140 it doesn't do anything wrong. No issues at all around town or under "spirited" acceleration. Could this be something like the MAF causing this issue? Or should I try getting it re-tuned again. Check my profile for mods to the car. It is cammed with a VRX5 cam. Thanks!!! [/QUOTE]
