I just got the turbo back from Majestic turbo. Cost for competion prep and clipping the turbine wheel was $135. It took about 4 days for them to get the job done. It definitely helped in spool up time. Now the turbo spools up as quick as a HX-40. I didn,t pick up any additional #,s of boost. If any body is having problems with spool up time i would highly recommend that you get this done to your turbo. (HX-35,HX-40,H2E it doesn,t mater what turbo you have this will quicken up the spool up. )
