I'm here making 425whp on 91 pump tuned by LJ himself.

Anyone running 550 injectors making 450?

Do you have any logs at all from your vehicle after the turbo was installed? You were running on a base map, and unless we know more information as to what was going on in the logs it sounds like there could have been endless possible issues.

im not blaming the tune at all.... LJ is the best and he is one great tuner.
i ran his tune almost 4 months no issues at all

it also could be a bad fuel pump installation, maybe no o-rings

I wasn't meaning you @whitefrs you're good people lol.

Good call on the fuelpump. That almost caused me an issue on the dyno. But like nelsmar said without a log diagnosing this over the internet is futile.

the fuel pump was good well i think it was but there was no way for me to tell im no mechanic, the car pulled crazyyy, that didnt feel like 7 psi, the boost controller wasnt messed with at all, and my mechanic did mention somethin about lowering the compression to about 9 or 10 to run higher boost and getting stronger rods and pistons, i have 550 injectors and running the gt28 turbo, the tune loaded fine but i didnt have any of my racerom features at all, like 2step etc etc which wasnt my main concern, i babied the car as much as possible but that didnt work so i guess i will see the results tommorow after they take the engine apart, and i was on 93 premium, i was gonna send lj the log but my car didnt even last 3 hrs before the knocking took place which really sucks,

and i used the 0w20 motor oil, full synthetic, did a oil change too, hopefully its the just the rods that needs to be replaced which isnt that bad, i just want to be on the safe side and get a reflash as well

i was stage 2 tune, with uel borla headers, intake , perrin pully before and was fine but wasnt satisfied,

i came from 3 evos.

slapping on a turbo to a NA engine will require a tune before you start boosting.
seems like you leaned out your engine too much from the turbo sucking in too much air without adding fuel. running too lean will cause internal explosions that you dont want. literally. your engine was exploding in all the places internally.

idle you want around 14.7
boosting / wot you want around 11.5 afr.

sorry your car is down. i know its a horrible feeling.



idling is not as important as your 11.5afr wot. I think that's where you went wrong. your wot afr.

I'm confused. The tune you were running after the turbo was installed was a not a turbo tune?

[Dipstik-sportech]

You say you babied the car and yet u say it pulled like crazy at 7psi? Did you have a boost gauge on it?

not sure who you mechanic is but if this car's fuel pump doesn't have the orings needed it will run lean and can cause a blown motor.

so ask them to check the fuel pump and take pics and post them

Is the person doing the autopsy the same person who installed the turbo?
