I bought an 06 GT that has a Powerhouse 67mm turbo kit installed. I'm the 3rd owner and the tune has been changed a ton of times by the previous owners (not dyno tunes) and it's got some quirks in the tune that I'm trying to track down. Main thing I'm seeing right now is it appears to me that the 91 octane base timing table (Borderline Knock Table) is all screwed up (too much timing at low loads, too little under boost). Problem is I don't know what the original Powerhouse timing table looked like, or any other 4.6 3v 91 octane turbo timing table. I need something that is known good (either dyno tuned or an original base tune) to compare to mine to see if it's as messed up as I think it is. It doesn't "need" to be a Powerhouse tune but it would be ideal.

Anybody willing to provide a screen capture, or text version of your 91 octane turbo borderline knock table? Thanks.

So are the internals forged?

Stock 4.6 3v engine. That's why I'm trying to make sure the tune is proper, so I don't throw a rod through the block.

Take it to someone who knows there stuff...

Stinger

I don't function that way. I'm a Mechanical Engineer and I've tuned 15+ cars, just not with SCT software and not a 4.6 3v. I can tune it, I just need to see what I asked for above first. Then once I get it close, I can put it on a dyno to fine tune it without grenading it.

Oh well more power to you! Literally!

Nobody has a turbo Mustang and has a way of viewing their timing map?

Go to the s197 forum, lots of turbo guys there. I'm thinking of doing a ON3 setup.

I see you got your answers at the s197 site. If you remember post your HP & TQ numbers after you get it on the dyno.

Stinger

Yeah, I got the answers over there. Previous owner made 465hp/492tq at 9psi.
