I just did a search but could find my problem exactly... So here goes.
When i step on the gas, the car will build boost...the gauge will go to the boost level i have it set at. But the car isnt pulling the way it should, its super weak. Its like a real bad hesitation. The EGT's climb extremely fast and would go over 900c if i didnt back out of it when i do this also.
But sometimes, i nail the gas and it pulls hard as $#@. And the EGTs are in the right range between 700c and 850c.
All of the threads ive read point to a boost leak, but my question is...if its a boost leak then why will it only do this sometimes?
And also if its a boost leak, will my boost gauge still read the way it should?
Mods on the car ( 93 Talon Tsi)
- Ported Big 16g
- 3" turbo back exhuast, no cat
- ARP headstuds
- Turbo XS MBC
- Custom FMIC 30" wide by 8" high
- All mandrel bent 2.5 IC piping
- K&N filter
- ACt 2600
- 95 Ex Manifold
- 95 o2 housing ported hardcore
- very mildly ported head
- Walbro 255lph fuel pump
- Stock injectors, stock plugs and wires, gapped to .027
the car ran fine when it was first all put together, but now this hesitation almost like "fake boost" happens more than "normal" boost.
somebody please help if soooo close to abandoning this darn thing.
