Mods in sig. Is 328.4 HP and 337.4 TQ good with no tuning at all? A/F was 12.6 and being that good would a tune even get me better numbers?

ALSO...................after dynoing my ABS and TCS lights are stuck on the dash. Reset computer a couple times, pulled ABS and TCS fuses, disconnected battery, disconnected TCS connector. Guy at shop told me is normal and will turn off itself but i put 130 miles and still on.

 

Those lights should have went off. Might want to check and make sure you didn't damage one of the sensors..

 

in the rear end you thinking?

 

Those numbers sound *slightly* low to me.

 

I was kinda thinking that too, A/F is good though 12.6 and powerband is flat as a pancake.

 

I've been told by local club members that sometimes the dyno screws with the electrics... my ABS light was on for a bit after a dyno run, then again... I checked under the axle and for some reason my ABS harness was disconnected (right above the diff housing)... Plugged it back in, took about 30 secs and the light went off

 

I will check that, crazy but may just be. I hate you for you numbers

 

I have 328 I wonder if it's different dyno's different elevation? My friends 02 SS with Kooks LT's and GMMG, Lid, and MAF was 327 there and my other friends 2000 Ws6 with Pacesetters, ORY, SLP dual dual, lid, and maf was also 328. All of us untuned at that same dyno.

 

Most likely sensor plug, if the dyno operator is not used to F-bodys with ABS, it is common to wrap the left rear axle strap around the rear sensor cable pulling or damaging its plug.

My abs light has been on for i dont know how long. It happened on the dyno too. Something with the computer sensing the rear wheels turning, but the front wheels not.

 

my light was on for like a minute after it dyno'd.

 

It is normal for the ABS/TCS/Ebrake light to come on during and after a dyno run, but will go off almost immediately after driving off the dyno.

Yes it is probably that rear sensor plug. It is white/red, jack the back of the rear a bit and you should be able to plug it back in unless it was damaged.

 

I hope I can just plug it back in. Thanks for the help guys.

 

The plug underneath the car gets pulled out sometimes for the dyno straps, it happened to me driving home, just plug it back it, its just a friction clip.

 

Mine as well, drove around to the back of the building and it went off.

 

lol my car did that after a BIG burnout and all i had to do was turn car off and turn it back on and that was it
