so guys i have an 2014 gsr evo x and my current mods are:

cobb ap with custom tune
ets intake system (big filter)
go fast bits (bov)
grimmspeed (bc)
complete 3" dump pipe
ams widemouth down pipe
garret 30-71r turbo pushing 25-26lb
forge wastegate on turbo(internal)
100%STOCK MOTOR INTERNALS
only run with 91 OCTANE pump gas

so the car has only 13056 miles on it as it sits today
since it was bought (from new)its been tuned and put all the mods mentioned before, when it had the stock turbo it was pushing around 28lb making on dyno 347whp and 456 wtq with no problems.

then i CHANGED the STOCK turbo for the GARRET TURBO 30-71r when the car had about 7457miles on it and thats how i daily drive for know my 30-71 is making 25-26lb current tune on dyno is 393whp and 410wtq and only use 91OCT pump gas

3071R making 393whp/410wtq on 91?

Was it dyno'd in 5th gear on a artificially loaded dyno?

I believe you and don't think you are lying. The dyno is.

Anybody that knows the lb/min of that turbo and the VE of the 4B11 would agree.

Plus you made 347whp and 456 wtq with the stock turbo? Nope.

What type of dyno is this? Land and Sea? DynaPak?

Maybe it was a typo on the stock turbo stats? Was probably supposed to be 347whp and 356tq. I don't think he should be going down in torque with an aftermarket turbo lol.

The peak torque will be lower from a stock turbo to a turbo like a GT3071, all other factors the same.

Again, lb/min and VE knowledge is key here.

ok man apreciate the feedback and its a dynocom and its like 1500meters above sea level what do you think my real numbers are?? i just ckecked out some dyno sheets on other cars and found a subaru not sure if its helpful it made 370whp 367wtq with bolt ons, im not sure if this is helpful i just want to have the right numbers 👍

s240

well yeah your wright but i guess my tuner prefered to go this way for some reason is this something not good??the car felt good and had a great start but when i got the 30-71 i told him to leave the wtq below 415 becuase of all the comments and the reading i have done about stock internals but what do you think about it you would help out a lot
