Can't get over 4,000 RPMs

I have a 2000 Audi TT FWD 180. I just got it about 2 months ago. The guy I bought it off of said he had the turbo replaced and a new timing belt. Whoever he had work on it did a horrible job. I've had to get a new timing belt tensioner, idler, belt, and cover. The timing was off by 3 teeth(not sure how it didn't bend a rod). I've had the oil pan cleaned out and a new tube that sucks the oil up I think(not sure of the name). Also, I just got a new fuel filter and fuel pump. These last 2 things helped the problem with the RPMs slightly. Before, I couldn't get over 3,500 RPMs. Since the same guy that did the work on the timing belt did the work on the turbo, I'm thinking there's something wrong with the turbo, but I don't know what it could be. Does anyone have any suggestions? Could it be something else entirely?

I want to add that my fuel gauge doesn't work properly. It doesn't go below 1/2. I thought the fuel pump would fix that but it didn't. The miles to E works properly though. The car did have the check engine light on, but it went off after I replaced the fuel pump. It hasn't come back on yet. The car used to have problems starting. Sometimes it wouldn't start and sometimes it would. The trip miles would go to 0 when this happened. So far, I haven't had that happen since the fuel pump. Not sure if this is useful information, but here it is.

Fuel gauge issue has been discussed over a thousand times on this forum. Use the search feature or even Google with "AudiWorld" as a prefix.

Spark, fuel or compression is the cause.
Use standard automotive troubleshooting techniques to determine the cause.
You need to run a diagnostic scan with Ross-Tech software & interface as part of troubleshooting with these engines.
The bad timing belt job could have bent a valve or two causing compression issues.
Again standard automotive troubleshooting techniques are required. If you are unsure, learn them at a community college or vocational school.
Alternately, take the car to someone who can troubleshoot for a fee. It will be well spent money.

Just saying

Its not standard auto troubleshooting for someone whose not an auto mechanic and not everyone can afford an expensive import auto repair guy. Hence, the reason for the forum. No offense, i just feel the guys pain.

This is just a shot, but since the turbo was worked on, I wonder if there is an air leak or restriction. I'd take a look at the air intake and turbo plumbing.
