I seem to be hitting my rev limit at 6500 rpm I dont get a buzzer but I get fuel cut to 1 rotor ( I think) should I leave it as is or should I get a new computer? Or how do I go about fixing this?

 

What car are you getting this on? If it's on one of your turbo cars you're probably hitting the fuel cut, which means that you're actually pushing more than 8.6psi at that RPM that it cuts out.

 

Its on my t2 I have a Fuel cut defender ! and I'm pushing about 10-11 psi so should I just leave it?

 

Maybe it would help to have a good description of what it's doing. Do you have confidence in your FCD?

If you're boosting 10+ then I don't see how it could have anything to do w/factory fuel cut.

 

what kind of FCD is it? my HKS acted the same way before adjustment

 

Racing beat defender, Its just like a brick wall it cuts out and then will rev right back, so should I get another fuel cut defencer. I have s-afc 720'secondarys greddy P.E. exhaust cold air intake "H" mount I.C. walboro 255 rewired. not catalitic converter. I dont rev it much but Ill be going to the dyno and would like to make sure I can get my full tuning in.

 

I'm having the same issue, with just about the same mods, I just have stock injectors still. I thought it was an ignition problem. Mine does it around 5500-6000 though, and not all the time. I'm only seeing 7 pounds but it will hit that rpm and just pretty much stop and sound like it's loading up, then when I get off the gas, a big bang and a 10 ft flame. It seems like it's just cutting ignition and dumping fuel.
