I just got internets after two weeks of no TSL...i was going through serious withdrawal.
A few comments.
The wrap job looks nice, as does the paint. The paint will last about 30 seconds, but oh well. More importantly, I would say take the wrap off. Thermal wrap will warp the DP since it's just aluminized steel...you can't create those sorts of temps and expect the DP to last very long...unless you like spending $300 on a DP every month or two.
Secondly, the manifold is more important for heat flow in terms of spool and power production. Not the DP....that's post-compressor. The DP should be dumping the gases as efficiently as possible.
Thirdly, the thermal barrier should be INSIDE the exhaust tracts, not retaining heat on the outside. I would say that you'd be better served pulling the manifold, getting it extrude honed or some sort of port and polish scheme, and then coated internally with a thermal barrier like a ceramic.
But, if you do that, then you might as well get the turbo exhaust housing done in ceramic, and maybe the pre cat portion of the DP.
But take the wrap off. Believe me, it's doing very little except increasing the likelihood that the DP will fail sooner rather than later.
Just my $0.02

Ok, I hope I answer some things here
I'm not getting a custom tune until I throw in a GT series a little later. Jak is going to throw a 9k tune on there and do some fine tuning from there. Once I go past the TD04 I'll be doing Nordic or SQR. I didn't get a bung because I bought this DP from someone on here (it's not new).

Alittle confused? Don't take this the wrong way, it's just the way it's word'd but are you saying you know of a tuner that does custom tunes off narrow-band?

People will disagree, but my feeling is that you should be looking at EGT's pre-turbo anyway. There's too much delay and uncertainty measuring post-turbo.
edit: yeah what everyone else said, meausure EGT pre-turbo. I type too slow.

|CooperS7777||EGT belongs in the manifold, thats the only place its going to be truly useful for tuning.|

|AeroDynamic||yeah 2nd bung for a EGT but its not needed to run the car... i thought saabboost was telling him he needed it simply for when he swaps the motor which did not make any sence to me.|

x2 ----- Wether you have a mailbox tune or a custom tune you should have a 2nd bung on for those Dyno days and tuning and hell in case you ever want to run a wideband o2 sensor setup on a daily basis.

|CooperS7777||Not all tuners do that, Im not sure who Boz has settled on or if anyone at all yet - but some simply dont. I have 3 o2 sensors in my car, one of which is a wideband but its not running all the time.|
|03-14-2007 11:10 AM|
|SAABOOST||My very first comment I was asking him he was going with a "custom" tune. I can't see a mail order being 100% right out the box. I thought I read in a different post that he was going to go with a "custom" tune, in which he would need the second pre-cat O2 bung , just like your going to need with your stand alone.|

To monitor while tuning.

|drewz airflow se||yeah in 95 there is only one O2 sensor|

|AeroDynamic||yeah the motor has nothing to do with how many o2 sensors you need.|
