quadzilla questions

Ok I have a few questions as well Ive had the Quadzilla in my truck for about a year and a half now and have recently done a few more upgrades such as turbo inj and a clutch. the reason I bought a clutch is because I thought my factory one was slipping ( turns out it was burnt and had little life left in it) so now that I have my new one in my truck it acts like its surging but loses boost and the turbo barks alot where as before it would just surge and make it seem like I was going over bumps in the road. Is that an issue with my tunning or is my waste gate having issues dealing with the boost? it peaks at around 45lbs and holds at around 35-40 lbs. Also the Backdown % is hitting 100% where as before it wasnt typicaly going above 40% and I have no clue what that even means Im assuming that it has to do with the turbo surge (bark) and that 100% is bad. any insight would be helpfull.
Oh and I've reduced my tune to 0 (stock) and it still does it thats why I belive its the waste gate and not tuning.
sig is correct save the clutch which is a valair DD ceramic

No that sounds like your just lugging the engine the "bumps" i felt were at 70 mph about 2000 rpm in 6th and they only existed around that speed/rpm range and only lasted for 5-10 mph at 80 and 65-7 they wernt therebut at 70 to about 78 they were real bad, almost like I was jumping on and off the throttle.
