Hello, I have owned my 02' for about a year and a half, when i bought it she ran great, but lately it has been problem after problem. Here's a list of my mods at the time i bought it:
4" Down pipe
3" catless exhaust
AEM Cold air intake
Auto Meter Boost gauge
NGK Irridium plugs
Turbo XS RFL bov
About 3 months ago i had some boost problems, so i took it to a local shop. They informed me my turbo was "coked" up. So i decided to purchase a TD 05 16G turbo ported and polished, i installed it myself. Once the new turbo was in i was still having a problem with holding boost, so i bought a silicone turbo inlet pipe and new power steering pump.
My current problem is that the car seems to be extreamly slow now, even 1-3k it doesn't want to accelerate quicly, it doesn't boost until a little over 4k and only hits about 5psi. At about 5k it makes a weird sound that i can't explain.... I don't think i have a boost leak and my exhaust seems to be good... Any idea's? AND yes i do need a tune, but why did it run good before and so bad now? Any input would be great!
