Went to the track yesterday and all I ran was consistent 12.8's. Here's my best run of the day. It was about 70 degrees and I had 18" wheels and 93 octane. My mods are:

3" Turboback w/testpipe
3" 02 Housing
10.5 Dual Hotside
AMS FMIC
GSC 272/264
MBC 22psi
HKS RS Intake
ACT Clutch/Flywheel
NGK 7ES Plugs
MR DV
Jestr M1 Flash

did you check for boost leaks?

EvoBroMA

what do your logs look like?

def. something wrong there... do a boost leak test. and compression test..

i can get some recent logs, but a few months ago i had all these mods except the Jestr flash and no 272/264 cams and I self tuned the afr with my safc2 and i ran a 12.9@106 w/1.8 60' ft. So getting cams and a jestr tune made my car only .1 sec faster???

can i get an estimate of what i should be running and trapping? and yes i checked for boost leaks, i only found one in my mbc but i saw that the hallman had a hole specifically there.

low 12's and trap around 113 (give or take)

that trap is consistant wiht your time, but with those mods that time/trap is no good something is wrong

i believe its the tune. im going to try and learn how to tune timing and fuel which i have the right ideas down.

i cant believe you would not do a compression test..

Datalog your run to see if your shifting is the cause (you can see how much time is spent shifting).

What do your 3rd gear pulls look on logs, that way you can see if it's slow or if it's your driving.

+1 to c6c6chevo's post. Also new cams may need to check into your timing. Why didnt you go with 272/272s?....

Id get a retune..... this time take it to a shop, not saying the jestr tune was bad but you may have other issues involved that only a shop can point out to you fastest.

1) The shifting is VERY slow. Good launch, but a poor ET due to poor shifting.

2) I'm not sure why you looked at your .1s gain when you gained 2mph. A tune and cams aren't going to give you ET - they are going to give you mph, and then it's up to you to drive it well enough to improve the ET. The cams are good for 3mph usually, and if you drive the same, then that's .3s. The tune isn't going to give you more peak power than the SAFC, because it's just a base flash. It will give more power under the curve, but that doesn't help much when drag racing.

3) I'd expect 110-112mph with those mods on a base flash, and then with that speed and that launch, you can do 12.2-12.4 pretty easily.

4) 24psi is way too much on 93oct. Why so much boost?

Not always true. I ran much faster traps 2 years ago when I had ALOT less power. For some reason now I am running faster ETs but slower traps. Someone explained it that I'm getting there faster, so I have less time to accelerate? Something like that . . .

I agree with #4. You could be knocking and pulling timing which will slow you down. Seems weird, doesn't it, that you can go faster with less boost, but it's true! I would log it again at that boost and make sure your knock is under control and timing is not being pulled. . .

Evolutionary, you're referring to improved 60's, but that's not what I was referring to in the part you quoted. If you gain 30whp, you should get 3mph, and then your ET will improve accordingly if you drive the same, which is what I said. If your 60's improve dramatically, sometimes you'll see lower traps due to getting there before you have time to speed up fully. That's what you were talking about, but in this case, his 60' was already fine (1.72).
