Re: 2G auto S/A daily
55lbs @ 25psi is a damn good amount of air. That car definitely has some 10's in it!

Re: 2G auto S/A daily
How are you reading airflow? If you aren't running a stock unhacked 2G MAS then the lbs/min readings are not going to be accurate. The GM MAF setups on DSMs are far from accurate.

Re: 2G auto S/A daily
How accurately can one log airflow using pressure?

Re: 2G auto S/A daily
Without an airflow sensor, you can't read airflow.

Re: 2G auto S/A daily
I had to just fix it. What happened was the mount came loose and moved the rod forward. So when we tapped it with the hammer it couldn't move cause the arm was fully depressed. As soon as I took the cotter pin and wastegate arm off the flapper closed completely. I've put 500+ miles and no hang ups.
I contacted a few shops and none could have an external setup done in time and I couldn't purchase one and have it in time either.

Re: 2G auto S/A daily
Too bad the tune is at noon, otherwise it'd be fun to swing up there and watch!
Good luck!

Re: 2G auto S/A daily
Just went through DB's checklist.
No oil leaks, fans in operating condition, coolant system bled.
Just need to zip tie a few lines to the boost controller, and zip tie the dipstick after oil change.
Should I gap my plugs to .24? I'm running bpr7es goal is to get over 30 psi.

I had to go down to .018 on mine before it stopped blowing out with this setup. I was on stock coils, however, BPR8ES plugs.

Re: 2G auto S/A daily
Nice that it was an easy fix. I gapped mine at .24. It wouldn't be a bad idea to have an extra set of plugs. Good luck tomorrow

Re: 2G auto S/A daily
From what I have read, brp7es with a .024 gap are the way to go. I currently have br7es plugs and have tried different gaps and I get knock every time. I am going to pick up some bpr's tonight and see if it changes anything.
Good luck with the tune, mine is scheduled for the 31st!
