My car stutters...

[thesoccadude]

Call me a newbie... I just installed my td06 20g, 2g mani with hks wastegate and some 660cc injectors along with some bc 272 cams. i start it up and of course idle is lumpy. the problem happens when i start driving it. it doesn't build boost at all, instead it tries and drops, my entire car jerks around. I've been told this was a boost look but i highly doubt it is.. i checked everything over... could it be i'm just running super rich?

You have some sort of way to tune the car? Or a chip atleast for the injectors?

[thesoccadude]

nothing... think that's the reason?

[Halon]

You're running 660's and a 20g without any sort of fuel control?

[brando]

well what is your fuel pressure set at? check all vacuum and boost lines. check your timing you may need to advance it a lil bit. check your plugs and if they are super black then you are running too rich and if they are white then your in need of more fuel. = and you might need to go dsm link if nothing else works.

welcome to the land of D.S.M.

Yea sorry man, if I woulda known you didn't have anything to tune your car with I woulda told you that right away. If you did a boost leak test and it checked out good then you should just need something to tune with and you'll be set.

anyone make chips to compensate?

Hope you have an eprom ecu.

Easy way to tell if your ecu is eprom or not is to see if it has an E on the outside of the casing.

However, that doesn't always mean it is eprom, in the 1gs sometimes it will have a eprom case with a non eprom ecu inside. If you can pull it out and open it, you will notice a chip on the bottom right hand corner of the board, that means you have an eprom.
