Just for fun. Recently had my 120k mile service completed for my 04 CTT. Clean bill of health and ran good sounded better felt great. Soon there after I happened across a gent in a Viper truck, coming up behind me fast flashing his lights blowing his horn and then pulls along side window down and thumbs up. I think to myself, " ...man I too old for this sh*t...", but give him a go anyway. PSM off, suspension lowered and to sport, 3 horn blasts and floor it! After a huge breath and accompanying roar and turbo lag, it's 1st gear and off we go! Needless to say it was fun. More to say after he caught up; "...that's not stock!" No it isn't I reply. So as I let him speed of I continue my leisurely sub 60mph drive home. Along the way I get PSM failure visit workshop. Okay...next up check engine light. Hmm...next up tranny lights up like it's in safe mode but is audibly and physically shifting fine. Temp is a little higher than normal and hmm...no more than .3 bar boost at WOT? Okay what did I break now? SO, at home codes pulled: 2187, 2198, 2281, 0299. Okay smoke 'em! Turn out I've manage to "break?" the old worn out breather hoses and the intake distributor is leaking! Gee Bevis...anywho fun weekend for me! So, while I'm in there I think I'll swap out the diverter valves and control lines as well. Just wanted to share.
Hi. Please watch the video and see if the boost is doing what it should. Video is taken from standstill in 1st gear, full throttle, up to third gear.trim.Dq9a7e.MOV
Hey guys, I'm trying to figure out an issue in my TT. Boost delivery isn't as smooth as it used to be. Under constant throttle application (lets say half throttle) boost will hold at .4bar for a number of seconds when it should really be building up, and then all of a sudden it jumps up to 1.2bar and takes off. Occationally it will jump up to 1.5 bar and hold until I let off (I don't hold it for long, and I try to avoid this). I've got an EPL K16 flash set for 1.2 bar, so 1.5 is overboosting. And then, sometimes I just can't get up to the 1.2 bar...it will max out at .8-.9 occationally. So far I checked the hoses at the N75 valve, they look ok. I found a big crack in the Y-hose, that plugs into the bottom of the DV's. I replaced that hose, and still have unsmooth boost delivery. What else might be the culprit here? Maybe the N75 valve is on its way out? Sticky wastegate actuators? I haven't gone underneath to investigate them. Any help is appreciated. Thanks, Connor
