Awesome!! What about manifold pressures, are you showing the gains with much higher boost or does it seem to be making more at the same psi?

Those gains are at higher pressure, but there is still room to go higher it seems. The billet wheels really came alive above what we were running on the stage 3 map

Also one fun fact, todays conditions were a lot worse than when we did the stage 3+ runs with the stock turbos:

Solid gains 3k -> Redline, minimal loss down low. Torque gains as much as 60wtq. Above 5500rpm through redline we gained as much as 50-55whp. Peak HP was at around 6200rpms, 30-35whp gains throughout the RPM range down low.

today was a success, and there is more to come
That is amazingly good news for you and for Tial. Well done !!!

Dude - you need to pace yourself. If the numbers are too good right off the bat it'll drive pricing up Sandbag it a little for the sake of the community!

If its 2000-2500, when its time to change out my turbos, you bet I will get these instead of the stockers, coupled with the HPF manifold and where cooking!

Price won't be known for a bit (as it's not finalized), but in my opinion it's right on target to sell well.

2k would still even be feasible... any more than that and i don't think i could bring myself to do it.

Man, haven't you guys ever heard of anchoring? We should all be saying, "it better come in under $1k"
