I recently just got my car tuned with hondata. We got all the full throttle tuning done, but only got to part of the partial throttle tuning.

When i floor my car, everything is fine and i can run through my gears all the way to 8500rpm with no problems.

When i put my car in first gear and roll from 1000rpm-7000rpm its fine, but then if i try to go higher, my engine starts bogging and my exhaust makes this spitting sound and it won't let me climb higher.

Why is it doing that? Is it because i didn't get all my partial throttle tuning done? Or is that a sign of valve float? I am worried because of all the stories i hear about retainers wearing out. I also am using toda b cams. Any help would be appreciated. Again, everything is fine at full throttle.

 

Who did the tuning? And did they tune for part throttle and full throttle?

 

its all in the tuning.

 

Well i only had 2 hours on the dyno. We completed the full throttle tuning and tried to tune the partial throttle with the rest of the time we had. I know we didn't do partial throttle tuning anywhere near 7000 rpm. I was just hoping nothing was wrong with my motor.

 

99.9% chance nothing is wrong.

 

my car is doing the same thing, it was only tuned for full throttle on the dyno, I have not gotten any street tuning done yet. Car runs great at WOT, but half throttle or constant speed, it bucks like a **** more tuning and she will be good to go.
