She's purring boys

[Zach]

After tinkering with my new car the last week or so trying to get to the bottom of a sneaking suspicion something just wasn't right, the New fuel pump and spark plugs arrived today. The pump I pulled out of the car was unbranded and slightly smaller than the walbro that went in. I think the one I pulled out might have been a knockoff because the copper plugs I had in the car for the last few days had white/grey on the tips and I could just feel that she had more power to give, almost like was only getting 90% combustion. New plugs in and pump in. Grounded the coils around the place and also grounded the engine to gearbox/chassis and boys she's responded so well. It took about 15 mins of easy driving before the ecu started to ramp things up again, then  I started giving her a good thrashing for half an hour or so and now she's just humming and is driving the best she has. I can feel she's making full combustion almost like the running gear has no weight to it at all, no mili second dead spots when I put my put down, just purring and boosting beautifully, the sound orgasmic. My plasma coils will arrive soon along with synchronic bov then I got to figure out a way to get my pod filter boxed and Im thinking its going to have to be a fab job then I'm gonna book her in with pappu for a humble 16psi road tune. I just knew she would have a slight vac leak or something because I could just feel it, I could feel the slightest bit of weight in the running gear so I started hitting potential causes one by one and Im experiencing that magical moment of joy you get when you have been tinkering with your car crossing potential faults off of your list and discovering all sorts of little worries along the way correcting them when suddenly you get it! and she hauls ass with love! I wanted to post about it because I know we can all relate to this moment and It will be encouraging to some of you who I know are still in that same boat trying to figure out whats wrong with your car. persist brethren and I hope you reap the rewards of winning the fight! I cant wait to wake up tomorrow and drive her to work!  v7 sti.

16psi is less than factory boost. They run like 18psi from the factory and will go as high as 20psi without caring. In stock form pretty much the only thing that makes them make power is boost, if you drop it to 16psi it will be about as fast as a WRX.

And the running gear will feel heavier.

good on ya for sorting it but im sure u can trust the boost control to your tuner , unless cars really unhealthy theres no reason for you to limit it that low.

I just assumed factory boost was around 15.  Had no idea they were factory 18. Thats great news

 

even 7psi boost wouldnt make the running gear feel heavier in the way that I mean.

also nice to know  she's only been boosting 12-15 since rebuild.  Brought car of a 50year old Philippine man
