there are only 2 problems, and i expected them both...when i started it up for the first time, it idled fine for about 5 minnutes then died like someone just turned off the key, after that it wouldnt idle under 1000 rpm without dying like that. 2 is an oil leak from the sending unit/feed line assembly, im just going to slather it in RTV i think in the morning because i have an appointment at the dyno at 2pm...with 42lb injectors it idled just perfect untill it died like that, and when i start it back up it starts up just fine, im sure its something the tune will take care of but any ideas whats causing that?
need help fixing bugs after vortech install
- Thread starter davins130
- Start date
The idle thing is most likely your pcm's adaptive strategy not having enough range of adjustment to allow for the 42's.
Remember, we told you the 42's would be best for your blown needs BUT they would give drivability issues without a tune.
While your talking to your tuner at the dyno, be sure to ask him about hot start probs with the 42's. If he has access to the start up fuel table, he can dial back a little fuel to compensate.
As for the leak, you'll just have to take a close look. Could be related to the blower install.
That thing ought be a beast when you get everything sorted out. Let us know how it all goes.

I had the same problems with my 42's. I have the start up fuel dialed back -28% and it starts as soon as I turn the key. Hot starts before used to suck and I had to pump the gas like it was a carb motor.

I had the exact same problems...
I thought i cranked those oil feed line fittings down pretty good, but they still leaked like a siv. I finally just took it to a local place that installs Vortechs...he said sometimes you just have to put some teflon tape on them to seal it even though Vortech says thats a no-no. As for the idle thing, mine would idle fine, then I would take it for a drive and it wouldnt idle for ****, turns out I had a small fuel leak by one of my injectors. Fixed that, now it will idle fine for the most part, a little suging but nothing terrible. Let us know how it goes...

went to the dyno today, got some bad news..Well i found out that the guy who sold me the kit gave me a 6psi pully instead of the 12 psi like he said, the oil leaked everywhere, it was going lean real bad maybe becasue of a clogged fuel filter(hasnt been changed in yeaaaars) the bung i welded in for the wideband had a weld that dripped on the inside and they couldnet get the sensor in and had to use a tailpipe sniffer, there was an airleak in the intake(made out of dryer duct because i havent gotten the elbow from vortech yet) and the torque converter they said was blowing thru or something and it wasnt getting me power to the wheels...so they didnt do much all they did was change the shift points and rev limiter, and tune it enouph to make it driveable and make it idle. they said to come back when i fix the problems and they would tune it again and all i pay is dyno time..Oh yea they tried charging me 25 bucks because i didnt have my pcm hanging out, what a load of crap.

Yeah man the dryer duct rig isn't gonna hang with boost. 
You need an inline pump if you don't already have one.
Fix that oil leak ASAP. Put in a longer adapter or whateber you need to do.
You can goop on some black silicone for a seal but it has to be clean and oil free when you put it on.
So you're saying you have a 3.33 pulley?
