Resolved Need Advice

okay something weird is going on i got my car running last night after working the bugs out of it, the new engine has new pistons bearings, emissions removed, slowboy boost controller. When the car start you have to keep your foot in it to keep it running and it stumbles and spits. The higher it revs the more vacuum it makes and it will never build any boost any ideas suggestions

boost leak and improper timing belt install?

 

[spyder678]

what makes you think that it is the timing belt. I have checked my timing 3 or 4 time now but i could be wrong

improper valve timing could cause the car to stumble and run like crap but if it's only off by a little bit it will still run. Are you getting spark on all 4 cylinders? Fuel? Compression test? We need to know these things before we can give you any more guesses ... it could be a ton of things causing your problem. Boost leak / improper timing are my top 2 guesses.

ya the car is firing on all four. The only reason I question the timing is I suspected that in the beginning and brought the car up to tdc on #1 cylinder then moved the cas back and forth and would get spark. I have my emmsisions removed on the car and a new boost controller. I have tested all of my sensors and my buddy who is working on the car with me thinks that it could be the tps since it didn't test out, but i don't see how the tps could cause to not spool up.
