But you did mention that if you where running a lower boost it will break up..so hows that running perfect?

no i was talking about before this motor, i had put in a junky motor to just test out the tune and it ran great both partial throttle and full throttle under boost, this wont run good with the vac line on at all. Once it starts to up fuel pressure in ratio to boost it just sputters out and wont even do anything no matter what the boost.

Again it could be the injectors are leaky or a boost leak or the program but i dont see how it goes from really good to bad when i really didnt make any changes to the setup at all. So again im gonna go over some things and quadruple check over things to make sure my end is perfect before getting the realtime. That way im not just bandaiding the problem if it ends up being something else. If you know what i mean

yeah i do too, im gonna be looking over everything this weekend. If i can eliminate everything for sure then ill just have to get the realtime to do some tuning on it, Its just soo jumpy that its weird. Thats really weird

I'm gunnin' for you ashton! lol just playing. It seems so far off before my car is back on the road. Glad you are making good power, more than I made with the VET. I am hoping to be more competitive when the new manifold gets put on. That turbo is pretty big no? Good for maybe 550whp?

yeah its a decent size, not overly huge but it does the trick and yes its good for about 550 whp

I would ad a o2 or gato performance intake manifold ... that would put you near if not at 500whp on that dynapack at the same 25lbs...
Good luck with the out come man.. keep us with news.
Cheers.

thats my next major modification once its tuned, yeah should definetly throw me over the 500whp mark at only 25 lbs and that would be best cuz as of now once tuned i think it will hit 500whp probably at the 28lb mark and 30lbs should make probably around 530whp but both of those would be right on the injectors limit.

^I saw where forum member Nissan Crazy made a thread about "gato performance". They make O2 style manifolds? o2induction.com don't do them anymore. I would like to have one, but they are almost impossible to find for highports. I'm going to get them to bore my stock TB to 64mm from 60mm and have the stock JDM intake manny matched to it. I think that will help out a little bit. Maybe I should have the runners ported?
