I have a 1.8t with turbo xs t3 t4 kit on it I just ordered a flashed ECU from Upsolute and I also got 440cc injectors comming soon but as of right now I have a TAP ECU and I was making 18 pounds of boost on the stock Ko3 and now I make about 1 to 2 pounds of boost till 4000 rpm's and then I still only make 5 or 6 pounds. I saw someone on audizine making 322 whp and 20 pounds of boost without internal engine work? Why does mine lag so much and why am I not able to make any boost? Could it be because of the injectors and the ECU or what is the problem? The car is much slower now and I def need some help. I've seen a couple of successfull T3T4 kits on 1.8's regaurdless of how much people on these forums hate them. If you dont like the kit just dont post anything, but if you have any good information please post away.

Can you hear the turbo spooling? do you have any exhaust or boost leaks? I'm guessing you are using an external wastegate now? is your wastegate working correctly? I would make sure everything is installed correctly.

Probably in limp mode.

I heard nothing but bad things about the turbo xs products, check the manifold for cracks and could be a leak somewhere or like what brancky3 could be limp mode?

You're thinking of the ebay XS Power line. Turbo XS is usually pretty reputable. He may have actually gotten the name wrong though. My Guess is he's using the XS Power type t3t4. Check for the basic- limp mode, boost leaks, wg etc.

to the original poster- When you say TAP ECU do you mean the "Total Audi Performance"? If so, this is not to be confused w/ CTapp.
