hi guys i need some help. i installed a hallman pro bc in my 03 evo last night and when i was adjusting the boost i went to high on accident and i hit fuel cut. now im not sure exactly what boost it was pushing but i know it was over 1.5bar which is almost 22psi. now i play on getting my ecu flashed but for now i need to know what the highest boost i can push with my stock ecu settings. for referance here are my mods
3" buschur turbo back
aem intake
forge diverter valve-recirculating
255l/h walbro fuel pump
hallman pro boost controler set at 18.85 psi and holding right now
apexi bar boost gauge
02 simulator-not that it matter in this post
17x8.5 enkei rpf-1 race wheels- not that that matters either.

so what i want to know is how much boost can i push on the stock ecu and also*** does anyone know how much awhp i should be pushing right with the above mods? if i could get some good post that would be very helpfull. thanks

 

Im running 19-21 Psi on 91 Oct and 24-25 Psi on 100 Oct.

 

I was running 21 psi with a stock turbo on 93....the car ran great...

 

Ambient temperature, altitude, and fuel quality all play important rolls in how much boost you can run on the stock map. However, I think the general consensus is around 18-19 PSI on 91 octane and 20 PSI on 93 until you get a flash.

 

so u guys are saying that with the stock ecu setting i should get about 20-21psi?

 

93 oct i have it set at 21 ... you can peak @ 22.. fuel cut shouldnt come in till higher... i guess it depends on your altitude also... Fuel cut you say? hmmm i hit fuel cut once this winter due to the fact that the hallman was frozen open.. make sure in the winter you take it apart and spray some wd40 on the ball bearing inside .. it hit 28-29 (not constant, just a spike.. it would have stayed if i left my foot on the gas) it feels like you just hit a dog.. i mean your going along and bamn brick wall.. throws you forward in the car and such , so unless you experienced that it wasnt fuel cut...

 

For whp id say 260-280 depending on your boost and ecu... probably the lower side since its untuned .. with the flash or afc you can reach 320 ...

 

yes it was def fuel cut. it was like i hit a moose not a dog.it snaped my neck . i like o **** fuel cut!!!!

 

really .. that cause you have all those mods and the ecu doesnt know what do do with all that air comming so it doesnt compensate with fuel.. needs to be tuned and no more cut..

 

yeah i know i do. thanks a lot guys

 

gook luck

 

ok one more question. what do u think of dynoflash mail-in reflash? any better one u guys would recomend?

 

anyone?

 

youd have to call Al and tell him your running a 255 and what oct.. the other mods you have shouldnt matter . for the 199 mail in flash it doesnt effect intake , exhaust and such..

 

i have talked to al b4. and david buschur. what i want to know is opinions? anyone
