V6 track passes
Went to the track tonite, made 4 runs (woulda made more, had a bad miss...). It was an 1/8 mile, and quite fun. I ran a crappy best of 10.75 with a horrible misfire, 156 BLMs (real lean). I was told that it calculated to a 16.44 1/4 mile... That's pretty crappy. Lucky for me, I have a AFPR coming early next week, Hedders, and cut-outs. I Have an Accel coil ready to go on as well (original one is dying). Just thought I'd let people know what times to expect if your ride is out of tune (or REALLY out of tune...). I'll be looking at 15's by May (14's with a little spray)

AFPR prolly won't cure BLMs off that far. You really should stuff the 3.4 injectors in there, especially considering you're looking at opening it up even more.

Its called Block Learn Multiplyer.
Basically it is a measure of how much fuel the ecm has to add to the engine to get it to run properly. 128 blm's are optimal. The ecm isn't having to compensate any more for the fuel. FBodTrek's 156 means that the ecm is trying to add a bunch more fuel to get it to run, so in essence, he is running lean.

A neat little 9000 dollar tool told me
I just hooked up the Snap on scanner and it told me so....lol. A?F ratio was WAYYY off too. I'm surprised the motor runs at all.

156 *with* 3.4 injectors?!?!?! You've got a *problem*, man. Time to test the injectors.

Where
Where would you suggest I look? I know my fuel pressure isn't right. The injectors are good, They were cleaned and the plugs show even wear (although show signs of an incomplete burn, coil not hot enough?). Any suggestions would be appreciated.
