Awesome. I was thinking about just deleting the wastegate all together with this,
GAR700213-0005 it's the non-wastegated version. Bout $300 online.

I wonder if anymore benefits would be had. I can't afford an aftermarket turbo, I don't have problems with this one for now just as long as it holds boost

Personally I wouldn't, I would save your money and put it into a decent turbo.

Kooper so u removed that line and just capped it off?

Yes I did.

It gave me access to a lot more boost and lower EGT's.
However, under WOT and sudden throttle let down it seemed the air couldn't let out fast enough and kinda romped on the turbo. "I have feeling this isn't good."

My turbo was already wearing out and I believe this accelerated the breakdown.

I finally decided to get another turbo. Went with a modified stock one "price was right" type of deal.

I can run 35psi up a 6% grade with about 950 on the EGT's unloaded.

Towing power was improved massively, feels like a new truck now. Got the wastegate vacuum line reconnected and everything with this set up.

Only problem I got now is past 21psi or so the CEL shows up. Guess I gotta get the over boost annihilator installed now.
