You are probably knocking pretty bad and your timing is being significantly pulled....Also, you may be running really rich...all added up will yield a slow car...The only way to know is for you to log what is going on...

All that said, I am confused why you are running an FP Red at just 23 psi. I thought the Red was more of a high boost turbo (e.g. 35R) that had some lag but big kick up top....

oh boy here we go again lol
my tuner didnt feel comfortable boosting more due to having stock cams and studs....don't really wanna get into this again....just wanted to know whats up w/ the boost

Colder air = denser air. This is why you are seeing higher boost levels; adjust your MBC for the boost level you are tuned for and save up your pennies and find a tuner that knows what they are doing

OK then just keep driving it ....Why would you need different cams to run more boost??? (Sounds like you need a different tuner...)

Sorry I can't diagnose what is wrong with your car, but everyone is telling you to reduce boost or not drive the car until you can log what is going on...Best of luck and merry xmas...

this is what everyone keeps telling me....i shoulda took it somewhere else in the first place, but didnt b/c i had the car there before....i hate switching shops....i was gonna try CBRD

try dtm, cbrd,sean ivey, turbotrix, mellon, jestr, 4wheelslide, petey turbo, buschur.....really anyone of them plus the tons I've missed will be able to tune your car right and I promise you won't be posting about your car being slow.

man with that set up your car should rip! 375 with a red is weak you should find a new tuner for sure!

This is a noobish type post. Why run a car at 28psi and it's tuned for 23psi? I hope you didn't run it for awhile like that.(I know it was a weather spike)

Get a laptop and cable

well, it's been so bad here w/ snow and ice that it hasnt been safe to really get on it....i did tonight, and thats what it peaked at

You should really look into getting some cams, they'd definitely help you out.

Find a better tuner or get a tactrix cable & post a log, otherwise it's not going to be easy figuring out whats up.

Ya 376 with the red is kinda disappointing...I was expecting more from it than that...I have the stock 10.5 hotside and am making almost 330whp.. go with 4WS, hes legit.

your probably knocking like crazy and the ecu is pulling a ton of timing

running 30lbs on a car tuned for 23 = new motor

Ditto, how long you been running it like this?

My 0.02!

Do not boost your car until you get a tactrix cable and log what the hell is going on. Or, get your tuner to look at your tune/hardware (can be your MBC or EBC failing) and modify it accordingly.

On another note.. as for the low output.... that is why it is important to get all the required mods (Studs, fuel pump, injectors, etc) before jumping into a big turbo.

I have seen three reds in Dynojet on 93 OCT.... they were between 400-440 WHP at 24-25 PSI. Hell, my car was making 370 with a boost leak and 403 with the leak corrected.

Good luck in finding the root cause of your situation!

Try to download your data log.

My car was tuned 24psi on pump. Almost everyday Im boosting from 26-28psi when its esp when its colder.
Im sure Im faster than 24psi. Also watch my knocks and internal logs in my Aem ems no knocks and timing pulled.
