Hey guys, I have a quick question. When im in third gear or higher and I give it full throttle, boost spools up to around 1.4 bar,(should still have plently left) and then cuts out. It will hold boost at around 1.4 bar but I can see on my A/F ratio gauge that the ecu is cutting fuel to compensate for the problem. What is going wrong? I have a chip upgrade but Im still using the stock wastegate spring. No other mods as of yet. FYI, the 2.2 20v with chip should hold around 1.8/1.9 bar consistently. Thanks for the help.
