Like mentioned above: find what voltage is getting to the fuel pump, check for fuel pressure, check your ignition timing. Yes, getting this thing on a dyno with a wideband might help diagnos this problem quicker and more accurately.

Any way you look at it, the car needs to be treated gently until it is tuned.

I totally agree, Im going to tune it asap at the "Performance garage" here. thy have a dynojet & a wideband 02.. until then im staying below 6psi
Im gona do a timing check today, if I was to retart it what degrees should I go for? and what is the stock timing?
thanks guys

I ended up slapping on a t04b hybrid instead and I have it tuned well now for 13psi......
No pingin nemore I think it was due to excessive intake temps.
P.S It made 296.5 RWHP

are you sure it's actual detonation? If it's happened two or three times your engine should already be screwed.

5.2k=+9
5.8k+12
7.0k--+13
that was for from the final 13psi run (the green)
here are my current settings with altered rpm points
according to the map..
all high throttle %99 (boost sensor settings)
2.6--- +2
3.0 +2
3.6 +3
4.2 -3
4.6 -4
5.2 +13

Kinda late response and you've probably already fixed it but:
I have a streetport with stock turbo, stock IC, stock injectors and stock ECU, with custom intake and 3" exhaust and also boosting 20psi, and i don't have detonation. I don't see why you're having such a problem with it. Just thought i'd add this to the thread.

I like you're green run a lot better. Mid 12 a/f numbers are pretty damn agressive.....I'd shoot for mid 11's. Maybe you should go with some 850 secondarys or 4 x 720. I'm impressed with the numbers beyond that though. You are maxing out the 720's by 290 rwhp.

I have few questions, and you guys seem like you could answer them.
What exactly is this pinging noise? What causes the engine to make this noise? And is it a distinct ping noise or is it a ticking noise?

Jeff Armann from Turbo Auto in Nashville built it for me.
real nice work... as you
SPECS: To4B V-trim compressor @ housing
Self ported WG --- creeps up to 10 psi
SHould be good for 380rwhp at like 18-19 lbs.
Im upgrading my fuel system with some 680cc pri & 850cc secondaries
