Ok so I was driving on a pretty hot day about 2 weeks ago, and I am crusing at about 40 in 3rd gear. and I go to give it some gas and bam! The car has no power and my stock boost gauge (knock gauge with my keydiver chip) climbs all the way to to top of the gauge! So I got off the gas and downshifted to 2nd gear and gave it some gas and absolutley no knock. So I have kinda been babying it so I would not get any knock. The problem with this is a don't have a data logger so I can't log it to see what it is doing. So I reverted back to maybe the injectors being bad, so I replaced the injectors with known good 550s and it did the same thing. Then I thought maybe my walbro was going out so I replaced it with my stock pump and the same exact thing happens everytime. It seems like at lower boost say 8 to 10lbs it knocks like crazy! And when I floor it and get it to 16lbs it just barley climbs up one bar on the knock gauge. Any ideas or help would be awesome! (Also I have no fuel contoller just the keydiver chip) /ubbthreads/images/graemlins/dunno.gif /ubbthreads/images/graemlins/banghead.gif
