O.K. so I already had the buschur turbo back, no cat, mbc, air intake, running @19-20 with no problems, then today I put the upper intercooler piping,blow off valve and mas pipe on and I cant go over 17-18 psi or Ill hit fuel cut, as soon as boost goes past 18psi boom, it hits like a ton of bricks. Also I have the afc, just havnt put it on yet, would that help of do need fuel pump injectors etc. Thanx...

 

I get rid of the BOV first and see if that helps anything out. There know to cause problems of this nature.

 

The bov is buschurs stock 1g, so I cant see that being the prob..

 

Maybe not.

Obviously, if the car wasn't doing it before your new round of mods it has to be one of those items causing it. If it were me I would swap the new stuff with the stock items untile you find the culprit. Then it will be easier to pin point whats actually going on, which sounds like fuel cut due to overboost.

I really couldn't say for sure though.

 

uhh...the BOV has nothing to do with it...you need a DynoFlash to effectively get rid of the fuel cut. Give the upper IC pipe and MAF pipe you just did, you are seeing the net results...you are simply over running the stock MAF, showing you your latest round of mods are working

 

Doesnt 17-18 psi sound kinda low for a boost or fuel cut..

 

Screw Dynoflash. Call Buschur Racing and they will help you out. Do you have their MAF pipe? Also, TurboXS has an economical fuel cut defenser if you want to go that route.

Please post back and tell us what your solution was. In colder weather, I hit boost cut like that near 21psi. Kinda makes race gas pointless. I don't have the BR MAF pipe or the UIC pipe yet, though.

 

I hit fuel-cut right after I installed a down-pipe. And at alot less boost. I assume that it may have been because it was spooling much faster I went with the DynoFlash, worked for me. The car runs excellent!
