Hey guys. I have a question. I put my car back to stock minus the HKS and I noticed that when I rev it, when the revs fall, there is a hesitation/shudder around 1500 rpm. I don't really notice it when driving, only when I rev at stand still. Any ideas on this?

 

What did you had on before? Was it tuned with your previous mods?

I have uprev. I just switched back to my stock map.

 

[QUOTE=SilverBullet;3261529]Give it some time. Probably the ecu is trying to do its thing

 

Yea, maybe. I also have an oil cooler. Would that affect it?

 

That won't cause anything. I installed a 25 row oil cooler on my friends completely stock car and everything is the same. Give it a few days and see what happens

 

So no other breather mods? Intake, header, HFC?

 

No other breather mods. Stock intake and exhaust excpect for HKS.

 

Is it just backfiring?

All auto G's have oil coolers as well
