If I blip the throttle and let off my new TA49 sounds like it has marbles rattleing around inside. My stock turbo never sounded like this. I only have 149 miles on it and it sounds really bad. I still builds boost ok but anyone else have this sound with their TA49?

I Played with the car all day today. Now I have no idea where the noise is coming from. It may not be the turbo at all. I am going to let her cool off over night and disconnect the serpentine belt and see if it goes away, may be in the belt drive train some where.
It sure is not affecting the performance. I did some 1/8 mile runs on country roads with the Tazzo computer and the new combo I picked up 7 MPH in the 1/8th.
The Tazzo computer was within .1 and 1 mph of my time slips in the 1/8 the last time I went to the track.
I was running consistant 91- 92 MPH 1/8 miles in 88 * humid heat today.
The lag on this TA49 with the PTE housing is alot compared to my stock turbo. But I also added a PTE FMIC so it may not be all the TA49 that is causing the lag. It's like lighting a fuse, 1, 2, 3, 4, then bang your gone. I am going to try to get my new 9/11 3000 stall and PTS extreme strret/strip trans in this week. The original 133,000 mile tranny is hurting bad with all the new power.
