Help with sputtering 3sgte, just wanted some opinions as to what it could be Options

[eggman40]

yesterday i was on the freeway with no traffic so i decided to give my car a little exercise. I jumped on the throttle at about 55mph... the car was in Wot and as it accelerated,but then i felt the car stutter for a split second. It almost felt as if i took the car down to about 80% throttle for less then second then back to100. It still reaches full boost at 15psi but just around 8 or 10 psi at WOt is where i feel this....



Anyone know what this could be? Is it the turbo? fuel?bov? any help would be appriated. thank you

you got knock response. lower your boost.

this whole "15psi is ok" that we get from the usdm mr2 guys, doesn't always apply to our swaps because we have jdm ecu's with more timing advance. we have a harder time running that much boost on pump gas.

if you make yourself a tvsv led's, you should be able to see when this happens.
