Posted this in the tuning area but it might have been wrong


I have just finished installing my new engine in my 91 GT. I am having major issues and cannot for the life of me figure it out.

My build:
DART sportsman block
D1SC Procharger with intercooler
SCAT internals
Forged Pistons
MSD dizzy set at 10 BTDC
90 MM Lighting Mass Air
90 MM ACCUFAB TB
mechanical water pump
Aerometer A1000 complete fuel system(Sump, pump, fuel rails, regulator set @40#) with 60# injectors
NJK plugs @ 35
Electric fan
MSD ignition box
TFS racing High port heads
TFS Intake
Super comp long tubes


Here is the issue.
Configured my tune using the tutorials (scalars and functions) on YouTube that was applicable to the 9al tune
http://www.youtube.com/user/tweecer
The car can idle but runs very lean and when you give it throttle it kicks more than a 2 year old leaving Toys-R-Us. It has a searching idle and I have the set screw full just to idle
It also has no vacuum. The lean condition and no vacuum sometimes means a vacuum leak but I have done the starter fluid and tried the cigar trick (smoke) and cannot find a leak( car has no exhaust so I cannot hear one). I did get it up to 2k and there was some vacuum for a brief second. I will be pulling the codes (throws a code a few seconds after the car starts) after this weekend but if anyone has any thoughts please let me know.

I am pullin my hair out as I cannot find the issue

How did you adjust your valves? No vacuum could be related to valves hanging open because
the valve lash is too tight because of improper adjustment.

Phoned Comp Cams and got the lash (between 8-14) Took the intake and the covers off(what a pain in the arse) and set the lash to 10 on all the valves(eoic method). Put it back together and fired it up. Sounds better but still no vacuum. I am pulling my hair out trying to figure this out .

I don't see cam specs or actual vacuum numbers anywhere?

I'm guessing the cam is fairly large.....

Yes not sure which one but it's one of these two.

I take it you are running a solid lifter on the cam? They are both hydraulic grinds is why I ask since you mentioned setting lash.

Which firing order did you use when you put the plug wires on?

Have you pulled all the plugs to look at them yet? I have a suspicion it is way rich.

Bottom line is your tune is either way out to lunch or you have a mechanical issue of some kind. Can you post a copy of the tune?

it the Ho firing order 137 etc

I have my tune and logs here
