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!!!

Tony , this is actually a common issue with cam cars . There is air turbulence that is messing with the maf . Now it can be tuned out , but your tuner need's to be in the car with his software running . The other thing would be to use a screen in front of the maf to straighten out the air flow . That isssue has always been there , you are just seeing it now .

Hope that helps :D
