:welcome: to IGOTASTI!!!

Those are really nice numbers for a stock turbo. I just can't seem to understand this, so I will ask. The ambient temperature was 113 degrees?!?!

thanks guys. the room in which the dyno was run was 118 degrees. gatta love the arizona heat lol
Dang, that is hot! I can only imagine the results if the ambient temperature would have been around 80 degrees!!

Intake temps were also 140 :( I would have made 380 with lower temps if not possibly more than 380 but im happy with 376 in this weather with the tune being safe with no knock

I'm jealous!!

+1 to that, man that's insanely high for the stock turbo. Hell, that's 20g/Dom 1.5 power on dynos around me, almost makes me want to drive out there and see what I would put down... ;)

But congrats dude, really good numbers and the car looks great. How much extra lag do you notice on the stock snail with the FMIC?

Sorry for taking so long to reply. I lost about 300 at most. but I think its tuned that was so it has more up top. either way the spool still feels almost the same

That's awesome dude, congrats again!

Edit: Just curious, did you do a baseline pull before you got your mods installed? Just curious to see the before and after. Thanks man!

Ok, i missed it...I thought that was very high for the stock turbo...
It's borderline pushing it. I've seen more, but usually they don't tend to hold up too well past 22-23 psi, unless rebuilt to be stronger. :tup:
