Hirochi Sunburst 1.8 Cvt Transmission

When under full and partial throttle the transmission seems to slip and it sound weird like a " bang bang bang"
(It sounds Like) the rpms go up and down. I don't think that that's supposed to happen. let me know in the the comments thread about I should do to fix this issue

Thanks,

 

I have to add something on that note, I think the cvt's gearing is way too short, going @ 100 kph the engine is doing about 3000 rpms which for a modern economy car is way too much (needs to be more like 2000). And when slowing down to a stop the rpm should go to near idle not stay the same.

 

I didn't know it should be somewhere near 2000 RPM's. I think it should accelerate and run smooth (something like a Nissan Altima)

 

Must engine get best economy while cruisong @ 2k. Plus, a cvt has to have more ratios and its whole point is to be at lowest rpm possible for maximum economy.

 

I wonder is this a problem on my end or do you have this problem too? Also there is another problem with a sport s trim
The turbo Boost doesn't give the full boost it stays in the negatives or 3.5

And to add on the problem there is a problem with the sunburst trim level Sport S, it doesn't give its full boost is either stays in the negatives of 3.5 do you have this issue to?

 

I don't have this problem... as you see my boost gauge is completely fine.
EDIT:
Did you mean when its @ 2k rpms?

 

Ok, do you know any way to get this problem fixed or, no?
EDIT: It stay like that the whole time and not just on this car but 1 other car I know of that is a mod

 

best guess is to use Safe Mode and if that doesn't work then reinstall the game (but I don't work at support so idk what else you can do)

 

Ok thank you!
