New Member and a strange problem with my TT S

[infinity]

Hey everyone I've been a lurker for a while and finally joined. My car is an 05' Turbo S cab and the problem I'm having is my car not hitting full boost. I have a tune so it should be onsistently hitting and holding 1.2 bar but it's only spiking to .9 I have some mods that you should know about if you can help me diagnose this problem. The car goes from .9 to .4 to .8 to .6 and bounces all over like that under WOT. The mods on the car are:

FVD stage 4 chip

Speed Tech 70 mm exhaust

speed tech 200 cell cats

AMS 1 bar WG's

DV's

Fabspeed cold air intake

Clutch Masters stage 3 clutch w/ LWFW

If anyone could help me with this I would really appreciate it. The things I'm considering to help fix the problem are. A custom tune, external WG's or new WG solenoids. That's pretty much it right now.

Here is a pic since I'm a n00b

Welcome aboard...the boost problem could be several things...first I would check for leaks, then plugs/coil packs. Is your ECU flash loaded with a flash loader? Can you revert back to stock?

Thanks for the reply, my car actually has a chip in it. I have the stock chip also. My shop installed new coil packs and plugs last week and also did a very intensive boost leak check and tightened up a few connections that were loose. So tonight I take the car out and it's a little cooler than it has been and about a half hour into my drive I hit the gas and the car launches me back and shoots right to 1.2 bar and holds there. It's running super strong right now but also seems to be running a bit lean. I' m totally confused at this point.

It is possible the ECU was relearning as you probably had the battery disconnected....I would check codes JIC, but if it runs great don'e worry about it.
