Today was a good day!

Congrats on getting into the 13's stock 8) ! When we were at the track during the NEX, my truck had a nasty overboost trying to run T2 22psi. I have been fortunate to have decent boost control with the stock set up. When I run T2 20psi, my boost never creeps over 21 psi... Follows Dave's advice and get a Mityvac on there to see what's going on directly on the turbo. BTW, you DO have a stock chip in there right? My truck overboosted like CRAZY when I bought it. Turned out that the previous owner installed a "hypercrap" chip :evil: . Overboosting stopped after it was out.

Ill work on the mityvac idea..

anyone else see anything good/bad in those datamaster runs?

I was just looking at the datamster. Are you sure you have a stock chip in your truck? Your boost target is 14.3psi, its supose to be 13.8psi in the stock chip bins I have looked at.. In 1st and 2nd boost peaks of your truck, it is reaching boost peaks on the verge of overboosting.

honestly, I don't remember.. I know I took apart the ecm when I was in pittsburgh, because I was getting ready to puton the ultimate, but I can't remember if I opened it up or not..

I will have to check.. this could be interesting..
I KNOW jimmy had an ultimate on the truck at one point, but i also know he took it off before he sold it.. I doubt thomas would have installed one..

What does it mean if there is no boost tgt at all? (0.0)

Re: Today was a good day!

1/4: 13.745 (ohh hell yeah!)
MPH: 96.31

So renz says my MPH is low

WTF? thats low? Shit, my 13.7 I made in my truck when it was stock was at 92 MPH

Either way, congrats on the 13's Im sure youre happy the truck still has some kick to it. :tup:

Which chip ID is on the label? Maybe try the chip in your Sy. I honestly feel that could be a problem, it shouldn't be setting the Boost target for 14.3 psi ...
