Anyone else have this problem?:

If I'm driving along at no particular speed and I let off the gas cause I'm going down a hill or just slowing down my RPMs bounce from 500 rpm to 1000 rpm and all over the place in that range. I have an EVO 93 oct xtreme tune and a JLT II intake.


I tried uninstalling and running it with the stock tune and I got a bunch of TSB work done and everything seemed to have been fixed so I reinstalled it all and it still does this. Thanks!

 

No issues here.

 

Have you talked to Fred yet.....that would be a good start.

 

I know I personally turned a lot of people onto Evolution with one of my posts long ago, but after looking back he more or less got my hook line and sinker. I no longer use his tune, and won't have anything else to do with him. Without going into any great detail, he's a sleeze-ball in my opinion. Go with a tune from a respectable company. Brenspeed or Ba ma.

 

If you do find out what's causing that to happen let us know. It might or might not be the tune causing it, it could be a vacume leak or something like that. I have to agree with the others B-speed or BaMa is the way to go if you find it was the tune. Good luck.
