94 octane not pulling
 

I've realized that my car doesn't pull at 4th or 5th gear, could it be because i have 57 trim? It just makes a lot of noise but doesn't pull hard like let's say 3rd gear
I'm still learning to be nice :P

Could be as simple as 4th gear just doesn't pull as hard, or something else like a boost leak so the turbo is "working" way too hard

Is this a new development, or has the car always behaved like this

It's cause you are Canadian. Have you datalogged it? Do you have any way of monitoring your boost and AFR during these pulls?

The 94 we have here in Canada is actually really good. I have experience with Husky only and i never see knock in my logs.

What RPM are you starting from? If you are starting from 2000rpm you are just going to be creating a whole bunch of load and yes it wont go anywhere for a while.

Now if you are starting at 4000 rpm in 4th you should be moving pretty quick in no time.

I have a AFR/Boost monitor .. Boost hits up to 9~psi which i think is too high because I should be hitting 7 MAX .. AFR is around 12.8~

I don't know i don't really do a lot of dyno pulls. I checked for any boost leaks and everything seems to be fine.

Starting at about 4500RPM and stomping the gas it doesn't go far. it's weird, It could of always been like that. I did a virtual dyno and it says i have 291HP 225 TQ .. I just realized now on the high way that after 3rd gear and slam it to 4th it doesn't go far lol. It was just a random question wanted to see if anyone else experienced it

I"m thinking it's probably my lack of injectors/fuel pump

You've got to post some kind of data log or dyno sheet.

94 here is awesome, use chevron if you can it is the only one without ethanol (atleast in BC)

That would effect every gear, your tuning doesn't change based on the gear your in, unless you have an EBC, then it's an option.

My only guess is that you are pulling more boost in 4th gear and hitting a boost cut that was put in your tune.

Holy shit lean.

Thats what I'm saying...

You need to contact your tuner, and get it to a dyno or street tune. That's unsat.
