lost on getting more power. 2000 camaro

[rpmspeed]

I'm trying to get some more power out of this 2000 camaro and been trying for hours but just seem confused or lost on the numbers.

Power 344whp, 335tq. dynojet that seems to read lower than every other dynojet i've been on.

Specs on car. 2000 camaro. automatic
tsp 224r cam. 224/224, .581/.581, 114 lsa, 110 icl.
springs.
tr6 plugs
1 7/8 long tube headers.
tsp 3in ypipe
k&n intake.
20in wheels
3.73 gear
2400 to 2600 stall

Here is latest tune i've flashed and a log

You may need to select a few more PIDs to give people an overall idea of what is going on.

You're losing a little bit of manifold pressure, so there is a slight intake restriction somewhere.

Also, your VE table defaults to common values - respectively for MAP columns - once you get to 5200rpm. You do not seem to be logging the AFR, so how do you know it isn't too rich / lean? Granted, no KR exists up top, but you may be out with the fuelling???

Lastly, 344rwhp equates to around 256rwkW in our language over here, which is a fairly stout result for the mods / camshaft you're running. There may not be a whole lot left in it.

cheers

thanks for the response. and the afrs are logged under wo2afr1 in the log. around 12.7-12.8 afrs.

Did you try a little less timing? Fuel looks pretty good as long as it is accurate - is that in the tailpipe? or up in the header?

These engines don't like flat timing and fuel either - try the attached and see if you get any better results... if you are still at it...

I would expect a little more out of that setup, but it really depends on the dyno... you may need to look for a mechanical issue because nothing in your log shows anything that is going to pick up very large amounts... hope that helps...

im actually sitting in the car right now going at it some more. customer wants it back tomorrow. and the wideband is in the header.

[BLK02WS6]

Let me know how it does... I would expect that setup to be about 370 to 375, so it is down 25 to 30... what muffler is in the catback?

looks to be magnaflow. he has a cut out. but not using it. I just ran that tune and got a lot of knock throughout the run for some reason. Here is a log

are dyno does seem to run low we get numerous people that just wants to do pulls and get like 40whp less than other dyno's they've been on. also this car is auotomatic with 20's for the wheels. I know it won't be a huge huge decrease but from my experience 20's will kill a little power shown on the dyno.

[BLK02WS6]

I would open the cutout and see if it makes a difference - if it is a flowmaster, I have seen those cause a 25rwhp loss numerous times... magnaflow is much better though...

I take it you are tuning by the PE, not the VE and MAF tables? Here is one with a bit more fuel coming into it... I actually dropped timing from what you had.

[BLK02WS6]

Well, if you run that much lower than other dyno's, there is your difference! Been through that before - had a Mustang dyno that ran lower than most other dyno's around - I would just tell people it is a tool to tune on and what matters is the before and after numbers on my dyno, not comparing to others.... then take it to the track for the numbers that really count. But I know that is not what they want to hear sometimes...
