Mine is running again. About two weeks now.
I either need to sell it, or buy a working wide band. The MaftPro is not easy to tune without one....
That is 3 years collecting dust.. And it seems to be just fine now that's running again. (Actually, sounds better than I remember.. The MasterPower T70 spools up pretty well to 11psi.. the wastegate spring pressure..)
The exhaust is very quiet too. I must have had a waste gate leak before. This gate is closed up tight off boost, and everything going through the exducer seems to make idle quieter than before with the bolt on T4.
Then again, the open dump pipe works great. I put a slash tip on it, and angled it to send the sound at the ground at an angle, and it is not very loud compared to many I've heard before.
At only 11psi, and completely un-tuned and running pig rich under boost, it's zero traction time above about 4500rpm. Still has the great stroker tourqe under that point, so it's pretty responsive, and will improve I'm sure as the MaftPro is adjusted and tuned right for this motor.
