I have the simple bolt on's, and an ecutek custom flash...Hallman mbc and aps d/v to hold boost; 1st,2nd, and 3rd gear spike at 22/23 and holds at about 20/21. 4th spikes to 23(sometimes 24) and sometimes it holds 21 to redline, and sometimes 23 at redline. Is everyone else's boost inconsistant like this? I could of swore when I first got my flash, I held more boost at redline( but that was a while back so I cant remember). But I have stock cams, stock fuel pump, and I think I could use a coil on plug ignition instead of the ****ty stock ignition. Im thinking first thing that needs to be replaced is my fuel pump to achieve more power up top.. any input? whats everyone else boost controller holding..?

 

ooo i get to be the first one to say it!!! Search.

 

hahaha damn beat me to the punch line

 

A quick search will answer your question and also it would inform you that you are playing with fire by not being tuned and running the stock fuel pump with that much boost.

Good luck

 

i wouldnt runthat boost on pump gas period

 

Im not a newb, ive been searching for an hour but came up with dead end threads, not answering my exact questions. I actually had my boost spiking at no more than 21, but when I got the flash the tuner turned it up as he saw fit.

 

i am tuned, custom ECUtek flash as stated in post #1. lol im not retarded.

 

boost spike s cause by diffrent engine loads in diffrents gears...and what rpm you start you WOT so theres your answer

 

thanks, appreciate it.

 

wow, so what im experiencing with my IX is normal than? weird. I guess i'm completely new to FI.

 

I run 23-24 lbs. in my ix on pumpgas, with a custom EcuTek flash too.. There is no problem running 24 lbs. on pump if the tune allows for it....

 

With that much boost you had better have an upgraded fuel pump or you may be leaning out at times.

 

different engine loads

 

Just read 14 pages of stew's thread, and it answered all my questions plus more, im not doing anything until I get a walboro.

 

thats not smart to run 24lbs on pump gas
