Message : I know they were wanting some of y'all to lllok over this and dignose their problems, etc... Sean, knows his turbos are going, but it would appear they are getting detonation too early. Anyways, I'll let them further address this with y'all. Here it is.

:

after 4500 rpm, how much boost is being held steady?


the wavy lines are signs of an ignition system that can't quite keep up with the air/fuel mixture, may the car be running too rich and/or the spark plugs are not up to par or the boost is not steady or a few other things.

If the car is detonating, yeah, the figures will drastically drop off since the ECU limits the boost to ~ 7 psi and also retards the timing.

with a stage V TTZ, he should be doing 340-360 rwhp and 370-390 rwtq
