How much boost is safe to run with no tune and just a full 3" TBE? 20psi?
20-21 is fine on pump gas.

My reply is to GTKage, did you reset your ecu (unplug the neg on the battery) after you installed your TBE?

After I installed my DP I got abnormally high boost spikes 23-26psi. But after I reset the ecu, the boost went back to normal 20psi tapering to 17psi.

Should I be concern since mine spike to 23-24 also? I only use 93 pump gas. My mods are TBE, K&N drop in, Walbro FP, and a base flash from Dynoflash with boost control. I don't currently have a MBC installed.
