Wait, I Can Explain My Low Numbers, I Promise!

[Chim55117]

I think we should have a thread that the guys who dyno'ed and didn't do as well as they wanted to can have a chance to explain!

I'll start!

Well Saturday was disappointing dyno wise with my VR-4 (243WHP). I cutting out at high RPM and barely building boost. Shane said he I was running extremely rich and I might have a boost leak.

The next day, on Sunday, I can happily say I found the boost leaks and fixed the issues.

1. Boost leak at intercooler piping clamp. Clamp had loosened off.

2. O2 sensor was faulty/defective, misreading and causing the car to run extremely rich. I replaced the O2 sensor along with the clamp, and reset the ECU. The car runs great now, builds full boost, and doesn't sputter/break up.

So what are your excuses? :)

heyy can i get your address again so i can get your wheel back

alright so i made 135whp because i had a huge boost leak. I found that my bov was crushed badly and it leaks out constantly. I can stick my hand over the opening of the bov and my car idles down like 500 rpm's. so i gotta find a new bov and it should be fixed.

Messed up tune from APR.

My numbers were pretty much on for what they should be, ~200WHP and 240TQ but my AFR's are not good, and nor is my bouncy powerband after 5k. Ugh

My parents aren't too keen on people we don't know well coming over, and last time you came over it was just me at my house.

There is a BP gas station next to my house.

Today is a busy day for me. Sometime this week at 7:30PM work?

My car has gremlins, and I don't have time to chase them.

I only made 341awhp :( I was running a point too lean (fixed a boost least and a turbo problem from my last tune). Followed shane's advice and raised all my fuel sliders 7% on link. Seems to be happier. And I have noo idea what my smoking issue is, it doesn't do it on the road. At least it looks fast and furious.

340whp is good power man, what turbo are you running again?

Just as a reminder, THIS THREAD is part of the reason dyno days exist! People need to get tuning into their modding plans from the beginning, think of how much you learned in like 10 minutes with your car! Little stuff that will help you keep it and you happy and healthy!
