I have no clue as to why I've lost the power. I'm going to describe what I can right now since I dont have a copy of the dynograph, so please bare with me..

If the motor compression tests ok I wouldn't completely freak out based on what you've described. That's a big difference though, and it is probably worth checking to see how healthy the motor is given that. Leakdown testing is also good, although a bit harder.

 

same dyno?

does the graph look the same? same RPM peak torque? same peak rpm?

lean is bad. Lean = heat, excessive heat in time = damage

 

Same dyno, just months apart. Its not a PRECISE replica, but its an average of ups and down just above 20HP.

Leakdown and compression tests are going to be done next week.

 

is it tuned? probably a source of another problem...DSM 450's on a stock p13

 

DSM injectors suck to begin with, tuned or not.

The point here really is, does the car feel slower? You'd notice a 20hp loss across the board like you'd notice a hernia.

^^^^^^For sure. More than likely the diffrence is in the dyno itself...

 

The dyno doesnt give anyone else problems, I dont see why it would me.

Forgot to mention its all tuned on a p28. These numbers are the best we could do from tuning it. My baseline (running shitty) was like 130 something, ABSOLUTELY horrible

 

does the car feel any different?

 

Honestly, its been running bad for like 2-3 months, I cant remember what it used to feel like. I put about 3-4 cars and still pulling on a f22 lude from a low roll if that means much.

up

 

post a graph....

if a compression test and leak test come out normal, then there is nothing to worry about.
