you NEED to tune it. I had it for about 2-3 weeks never tuned it. Runs fine at first and then goes to shit because it HAS to be tuned.

or you can run it without the tm adding a vc and map sensor. no analog, just timing and fuel. works like a charm.

You need to set up a date with me so we can straighten your car out. If you're doing it nick's way, it always ends up running like crap. I've been through this countless times and have helped out as many guys who came from Nick with the exact same problems as you.

i spent over a year fixing mine. when i finally fixed it, i found out that Dana's solution was a much better way of tuning the car. So.... talk with Dana and stop fucking around with MPI's way.

I've told about 10 people who were having trouble to go to you, and all of them ended up golden. After my new setup is done, you're flying to NM for the tuning and dyno session. :)
The FM clamp is needed if you want your car running well with the MPI. If you want to tune the stock injectors, do it Dino's way with the MAP sensor. If you are happy with the car out of boost and just want to add fuel and retard timing, you can do it my way and basically use the unit as a secondary injector + timing controller. Both of them fix the analog issues that are common with running it Nick's way.

damn i must be lucky then lol cause i'm tuning it myself and haven't had problems like that yet and i have been running it for a little over a yr now. my only problems i had was i had the old tm and didn't know about the resistors and also the fuel cut just reduce the fuel upper limit. i got mine down to 4.6 something i think. plus don't use the universal o2 sensor if your o2 sensor goes out. well the man one on the exhaust mani. im using it and my tune is fine when the car is completely warm i mean like 10 min minimum after sitting for atleast 3hr. if you don't warm it up long enough it stumbles and almost dies. its wierd and a pia o and dino i got an extra injector setup but i don't wanna jus chop up my existing fuel lines can you like pm me what parts and price it would be to hook it up correctly. basically no jimmy riggin lol
