I did 12.9 with stock heads and no intercooler.

Hi Bill, any luck with finding that skip after chaging out the coil packs?

i saw and did hear the boostmobile running at idle sound good and very responsive .for sure if he gets good traction i will post good numbers at the track .to bad the weather was not for us drag strips guys

Getting a handle on this low rpm low throttle kr. I crawled under and checked the rear knock sensor one night..seemed to intensify the KR the next time I drove it. Checking by yourself is tough.

Today.. I got a chance to get some help.... say Hi to Matt and Nick..lol. Before doing anything..I noticed the rear wiring was loose.. because when I messed with it..the seal had fallen off it. Added the seal and the connector seems to be staying still now. So far...no KR Time will tell if it was really that simple.

How is the car responding now?

He told me he still has the KR and the knock sensor wiring was not the culprit.

The really odd thing is that when he monitors KR, the timing does not change when the KR is happening. WTF is with that. :?

If the PCM indicates 5 KR then that must mean that it has retarded the timing 5 degrees but Boosty says that when his scan shows a few degrees of low rpm KR that the timing does not retard.

oh now thats wierd :?

Thanks for responding for me Paul

The rpm and load are at a low level where timing bumps around as load etc increases slightly that the retardation from KR is impossible to notice. The wiring could still be suspect as are the sensors and everything under the hood. What I do know is that no amount of high octane fuel or timing retardation through the timing commander and even a gear change (change in load) changes the KR. Aka..I have a high probabiliity it is false KR. Soon as I can get a moment..I'm hitting this hard.

Meanwhile.. we frequently hear that the 3800'* love timing. Having the Caspers Timing Commander, a properly tuned PCM and an Aeroforce gauge can be quite enjoyable.

I'll have a new pb, the question really is..once I have slicks.. where will my pb end up?

Meanwhile..I happened to get these (dead camera batteries) the other day. These...minus picture is a set of spring blockers.

Spring-blockers won't help on your launch. They don't even touch the coils when the ELC is tricked.

In fact, I tricked my ELC to install them.
