They're OK, but once the 400rwhp zone is reached, other LT's seem to make more power than them. I swapped them out and saw gains.

Thanks guys! SouthFL, I am OK with my combo and am aware there are better LT's out there, but my wife mainly drives the car and it's raced on occasion(not that much) although I appreciate your help, I just want to make sure the current combo is making ALL it can!

I am not TOO versed on tuning so Im stuck with trying to figure it out myself or pay for a dynotune and still have PT to tune.


AARRGGHHHHH!!!

Yeah, you're fine with them, I was just answering TroubleWine3's question.
Good luck!

Well, did some work on it tonight. Turned around teh set screw on teh TB so that I can adjust the idle a little and help with the surging, replaced my O2, and pulled a couple plugs. Here they are







Pretty fouled. I believe the stock tune was soo out of whack it fouled out my plugs over the course of driving it before. Now I gotta get this Part throttle stuff down!!!

Anyone wanna help with that??

Those #'s are NOT correct for an FM13 car. It should be at least in the 380's even without tuning.

Definately got some troubleshooting to do

Damian See above^^^^^^

I think that is part of it! I did just realize all the ones I pulled were fro the drivers side(side that had the bad O2 I just replaced) So I'm not sure if all 8 are like that or only the drivers side. I will pull some from the passenger side and report tomorrow!


Thanks

Every dyno is different . I do agree that they are low but a good tune will do wonders . THe o2's were bad then you should see a little more as well. I could not be happier with the f13 in my car.

Hey I am looking through your dyno-pull...

-I noticed your injectors are showing 80% duty at 4650rpm and hit 100% at 6000rpm, just an FYI...

-Your are locking a positive LTFT of 12 at WOT. When you hit WOT your last postive LTFT transitioned through will be added to your PE value (as a percentage).

-Looking at all your LTFTs it appears you car is running lean (8-14%) and the PCM is playing catch-up to add fuel.

-Your timing starts off at 29.5 and drops to 23 (4700rpm) and then goes back up to 27.5 (5500rpm). Did you have to do the 23* to stay out of KR???

Other than the timing being a little low in the mid-rpms and injectors being MAXED I am not sure where your missing HP is. I am going through your current tune right now... None of the above should amount to much...

Im not sure. I have not messed with the spark advance. Yeah and on the dyno it was lean also, but Im not making enough power to max the stock injectors! I replaced the bad O2 last night(drivers side) and will do a street pull tonight and see what you can make of it. Thanks for all the info. VERY helpful!!!!

Also bottom of intake tube was not on TB. Fixed that and cleaned the plugs and got another .hpi if anyone is interested in looking at it. I think that was part of my problem!

Prolly why the plugs look the way they do...too much fuel. That would make a motor seem pretty lazy, but that doesn't agree with your a/f readings (are you sure they were high 13's and not high 10's?)

I will get the dyno graph today! Thanks! The new file was much better than the old one with the new O2, and fixing the intake tube, and cleaning the plugs.
