finally got the car started!!!!! basic tune question

ok so heres the combo

stock bottom end
performer heads with 1.9 valves
crower 15511 cam
performer rpm2 intake

with a base hellion kit

install went pretty smooth
i do have an exhuast leak between the down pipe and the turbo that i need to fix .

but my main question is like base settings f/p , timing and stuff ?

i know i can clock the mass air to help with idle and stuff

should i just set timing at 10* , or are you guys setting it and running timing locked out ?

fuel pressure ?

any ideas , experience or info would be great
thanks

Before I go my car tuned I set my fuel pressure at 38 and lock the timing in at 20*.

Same as above---just stay out of the boost until you get it tuned.

How are you planning to tune it?

You might look into this: http://www.xpinnovation.net/products.html

The stock computer and a TimingLock will work great on a setup like yours.

if you want to run spout in set timing at about 5* and then turn it up a degree or two if you aren't getting any knock

Until you get it tuned, definately keep it fat and the timing down just a bit...I just set the timing at 7*, put the spout back in and if you have a fuel pressure gauge, adjustable regulator, and an FMU, I'd set the fuel pressure to about 90psi at WOT....Probably won't make the most power with these settings, but will keep it pig rich and in the safe zone till the custom tune...

You did not mention your fuel system! What injectors are on there? Timingwise you have heard a bunch of reasonable suggestions. My setting fall into the same range: 18 BTDC with spout out or 6 BTDC and put spout back in. The idle stuff is likely to be MAF/injector/fp related. The turbo stuff should not affect idle.
Unless you have your fuel system upgraded to 255 lph pump, matched maf and 36-42# injectors, don't let it get into boost or you may be pulling off your stuff to change headgaskets etc.

sorry guys .....

my fuel system is a 255 pump , 42lb injectors and an aeromotive regulator .

the meter is the c&l unit that came with the kit .... havent messed with clocking it but the car is idling great as it is now ....

just sittin on jack stands ...... 10* timing with spout in rite now ..... f/p is like 32 with vacum .....

is it safer to run spout out now and set it at 20* ?

thanks for the info guys ..... if i can get my cooler lines ran , im going to creep around this weekend and ill get ya some pics

A few words of advice:

1) Add an inline pump to your setup. You're going to need it.

2) Just leave the timing at stock, put the spout back in it, and DON'T STEP ON IT UNTIL YOU GET A TUNE. Real simple.

I'm not sure if I'd run 20* of locked out timing yet....I'd just set it at 6 or 7* and put the spout back in....I've experienced with several turbo cars, and usually they perform and drive better with the spout in.....Now, you say your going to "creep" around this weekend...Dont fool yourself, you have new power and will be tempted to get a heavy right foot....Do yourself a favor and set you car up rich on purpose just to be safe until the tune...Any time I've put a blower or turbo on a new setup, I've always ran low timing and alot of fuel pressure at WOT until I could get to the dyno....I've never had to change headgaskets or split a stock block....You don't want to have to change headgaskets a week or two after you just put on the new kit...

The most conservative way with the timing is to set it at 18 and leave the spout out. They do run somewhat better with it in but if you do that, no more than 6 BTDC. Driving it around is a little hard not to get on it that is for sure but don't. 255 lph pump should be fine imho-pretty common setup.
