E-Tank Posted March 1, 2010 Share Posted March 1, 2010 Had Infamous tune my car about six months ago. My power mods were catless UP/DP and a Blitz panle filter. Recently installed a 3 inch CBE and an HKS BOV (set to to recirc.) and now I seem to be over boosting pretty significantly. According to my AP I'm seeing peak levels of just over 18psi. I was under the impression that I wouldn't require a new revision for just a CBE and a new recirc valve. I assume it's the decrease in back pressure that's causing the spike. Is it dangerous for me to run boost at thses levels with my lil' VF40? Link to comment Share on other sites More sharing options...
Ridgeracer Posted March 1, 2010 Share Posted March 1, 2010 Do you have a datalog of this.? 18 psi peak isn't that bad with stage 2 mods and 93 oct. "Gimme mines Balboa...Gimme mines".....Clubber Lang - Mr. T Link to comment Share on other sites More sharing options...

GTTuner Posted March 1, 2010 Share Posted March 1, 2010 Are you hitting fuel cut? I cracked a ring land bouncing my car off fuel cut. Be careful. Link to comment Share on other sites More sharing options...
E-Tank Posted March 1, 2010 Author Share Posted March 1, 2010 I will run some logs and post them. The reason I was worried is because before the CBE and BOV I was peaking at around 17psi and now I'm seeing 18.5. I haven't hit fuel cut, but I also haven't really been dogging it at all.

NSFW Posted March 2, 2010 Share Posted March 2, 2010 18.5 psi is not unreasonable, if the car isn't knocking. Since you're running a tune that was designed with less boost in mind, you should do some logging to verify that it's not knocking at the higher loads you're now hitting. You might be fine, you might not, you don't know until you verify. Link to comment Share on other sites More sharing options...

Be careful. it was the overboost before the fuel cut that did it, not the fuel cut itself On the search for a new DD... Link to comment Share on other sites More sharing options...
