This is a wot run, I'm on stock turbo, stock block. Full bolt ons besides down pipe and fuel system (if that counts). My reason for posting is that I feel like I'm over boosting, this pull says 28 pounds, but when my tires spin I hit 30, but only when my tires spin which is rarely (only when wet). My injectors is my biggest count concern because usually at wot I hit in the upper 90% and rarely 100%, and today I saw it hit 110% for the first time. I usually don't beat on the car and I occasionally do wot pulls. I'm not going to upgrade my turbo, I make 301whp. Retune? New injectors? Help!

 

Too much injector duty cycle.

What pump?

 

Stock pump and injectors

 

...but when I do, I go 144mph.

 

^^ lol.

Well im pretty sure youve maxed out your injectors. Might be able to drop some cycle by putting a pump in it, but injectors and pump should be upgraded.

 

the oem evo 10 pump will support anything the stock turbo can dish out on pump gas, easily.

 

What fuel are you running? 28-30psi seems like a lot of boost unless you have really good pump gas in your area.

 

93 pump gas. Stock turbo

 

yeah, that's what I heard. Just minor bolt ons and tune is all I have. No injectors or fuel pump

 

That's a lot of boost for stock injectors no?

 

Taper down your peak boost to something like 25. Save your rods. Plenty safe with 25 otherwise as long as your tune is good

 

Time to upgrade.
Or lower boost

 

is this using a Cobb AP tune? If so, get a pro tune and problems will likely be solved.

 

Your stock pump may be going out. Replace it with an Asnu drop in pump and go from there.


I'm still concerned with the amount of boost. Its running quite a bit.

 

I'm my experience, no matter the tuner, there is no perfect tune. I always log after being tuned and usually have my tuner make small revisions. The way a dyno loads up the motor is different than real world conditions, not to mention seasonal changes. I'd suggest doing a proper log and having your tuner check it and make some revisions. Seems like it's being pushed harder than the mods you have can support safely.
