So I set a mission for myself today when I got off work. Figure out why the hell my car is sputtering at wot. So i started by taking the boost down to where it barely does it. 16psi. Then I took the ets tmic off and put the stock one on. Still there. Then I took my custom fujita intake off and put stock modded box back on, still there. The I boost leak checked it and sealed everything up. Still there. Then I cleaned the maf. Still there. Then I tried new plugs gapped at .35. Still there. Then I regapped at .28. Still there. so I regapped to stock .32. Still there. Then I decided to go back to the original plugs. Still there. I even tried putting the stock pump back in and guess what, still there just worse.
At this point Im way frustrated.. Hours into this and still accomplished nothing. I decided to try a few things that addressed the cold issue. So I taped over the hole I drilled in the hood over the filter. Still there. Then I decided for s**** to just stuff the whole ram air with towels to see if keeping most of the cold air outa the engine bay would do anything. STILL THERE. DAMN IT.
I was hopeless at this point. Then i started thinking about my previous cars and what if any problems were similar to this and what it took to fix it. I remembered that once i hit about 28psi in my evo it would do something very similar. It was spark blowing out. Well the fix for that was new plugs and taking apart the stock coils and stretching the spring inside each individual coil so that you could get a better contact. So on a wim I decided to give it a try. I pulled apart each coil and stretched the spring just a little. Enough to where it took a little bit of effort to get it back together. Put it all back together and went for a drive. TO MY SUPRISE IT DIDNT SPUTTER!!!!! So i turned the boost up to 18psi and still no sputter. Oh s*** did i stumble upon something or what? I was so stoked. Then for s**** I turned the boost up to 20psi and to my suprise still no sputter. So i headed home and put the ets tmic back on, and the sri. Went for some pulls and man the car is straight up MOBBING at 18-20psi. Air fuels were around 10.4 which means there is room for more. I cant wait to get my full turbo back on this hog and hit the dyno. The best part is it pulls all the way to redline and boost holds strong.
Here is my mods list:
custom fujita sri
ets 3.5 tmic
test pipe, muffler delete
pg cdfp
map clamp
bc 18-20psi
aem uego mid 10s afr
Im not saying this is gonna be a fix for everyone but it worked for me. Do me a favor if you are sputtering at wot, give this a try and tell me if it helps it.
