we definately spent a whole lot of time on your pcm. hours at the dyno, plus lots of time the days before, and the day after, and i am doing some more tweaks tomorrow to get your shifting the way i want it.

you picked up about 32 crank hp, which from a camshaft, cold air, and some pcm tuning alone is not bad. if we spent another few hours on the dyno, we might be able to get 5 or so more out of it, but at 100/hr i doubt you want to.

...you're definately right mike. I'm already up to my ears in debt. As I said earlier I was just thinking a bit too far ahead of myself.

Where's his timing at? I would think you could get more out of it with more tuning.

Yeah no doubt, something is a little off with Eric's car. Seeing as how I dynoed NA with all the same mods minus the cam & TOG's and put down 176whp. Can you post the graph? How many miles are on the car? I'm sure that you could squeeze out a little more. Also was this done on a mustang or dynojet?

[MilzyZ34]

well the only things i think holding his car back were ... humidity was 100%, temp wasn't too bad for lately ... 80's, and i hate to be negative about someone else's product, but his heads are quite restrictive on the exhaust. i didn't have time to get them flowed, but i know for a fact ours flow a lot more.

the car has 84,000 miles i believe. he's running Mobil 1 oil.

this was done on a dynojet, but one that gets calibrated regularly, so not an Egojet. a Mustang load-bearing dyno would be nice, but the closest one i know of is in detroit.

i have a jpeg of the dynoruns now, can someone host?

3x3 - i'm not going to post our timing table we put in, but i will say that it's 3 degrees over stock.

you can email the dyno runs to me and I'll put them on our ded. server...

i know those numbers are a little hard to read in that image, they say ...

181.5, 181.1, 183.7 for power

183.2, 180.8, 185.8 for torque

Can you get the before cam sheet?

owner has that one, i don't have it

I'd be willing to bet if you leaned it out, you'd pick up a good amount power.

we tried some things to lean it out, but it didn't have an effect. as i said, we anticipated about 5 or so hp from leaning it out to a flatline of around 13.0.

ok... assuming those runs were back to back.. you really need to let the engine cool down to normal operating temps.... then you will see the real difference the tuning makes. also the power curve is nice and flat... comparing it to my dyno sheet.

there is alot of power under 4k rpm that is not normally seen. also the power stays consistant all the way to redline.

I think the overall increase in usable power is more important than a apex or spike at one point. This is exactly what I was hoping to see.... also keep in mind that "most" with CAI and exhaust should not be seeing 165 horses. that is 20 WHP from Intake and exhaust??? to get 165-175 you will need headers and other bolt on's... unless you are below sea level and dyno'n in 70 degree weather.

the torque seems low... i would expect more around 200..... also what gear was it dyno'd in.... I have found that 2nd is more accurate from a torque standpoint. it reflects closer to 205 and 175 crank TQ over HP.

What were you tuning with? Powertuner? ICCU?

Another cheap trick, not the best but would work would be to port the maf and remove the screen.

I'll get that for ya soon. I don't know how much you'll be able to compare though because it was done on a mustang dyno. I plan on heading back to the same place to have it dynoed there as well.

It needs to be leaned out. Your running too rich on the top end and if your running 3 degrees more advance than stock your also missing out on power. Tweak these two and I wouldn't be suprised to see a 15whp gain.

I dynoed 184whp & 194 lbs-tq a couple months back. I have another thread on this but I'm right around 29 advance timing. I do believe there is even more power potential with upping the timing to 34-38. Play with the timing and wideband it to keep the fuel in check and of course look for KR.

if you want one of these.... PM me. just pay for shipping and it is yours!

To inform the public, removing the MAF screen is a bad idea and can cause issues such as misfires and causing your car to run very lean. You don't need to worry about outflowing the stock MAF in any way for an NA car. Sure, you can tune around it but its trading off one thing for another... a little more airflow and running pig rich just to keep the computer happy.

I'm not saying there're people out there who've had no problems with removing the MAF screen, I'm just saying that in a car with many bends in the intake tract its a bad idea. People get away with it in LS1 cars all the time because they tune their car for it and the intake path is dead straight.
