Yup sounded like a leak to me, good thing you found it...nice job.

Doubtful it was tuned with that boost leak. If it was his afr would probably not be 10.7:1 now, would probably be 6-7 points higher.

Keep us up to date.

I'm not familiar with that particular tuner's style, but some tune low 11s - 10.8 or .9. Always a possibility

Issues still remain. The car feels good while out of boost. Drives around nicely and feels responsive. Once I get into boost though (mainly just in 3rd gear) it just feels like it is falling flat. Did some 4th gear pulls from 65-80 and whatnot due to passing and that feels alright but not what I would have expected. Trans is definitely not slipping.

Think I should spend the time to pull the plugs and do a compression test?

Wouldn't hurt to do one at this point.

So I did a compression test today. Took a bit longer than I thought but I am super happy with the results. All within spec and not more than 2psi difference across the cylinders. Also swapped out the bpv gasket as well as some new iridium plugs. Then I proceeded to clean the MAF sensor. Haven't had a chance to do a pull yet, but the car is idling better and fired up quicker. Updates soon, hoping my issues are going to be a thing of the past.

Update:

https://docs.google.com/spreadsheet/...Wc&usp=sharing

Here is the most recent log. Spark plugs are changed, new throttle body hose, good compression and its still slow. Any advice?

Thinking it might be a boost leak somewhere and the turbo is overworking to hit target boost levels, but dont really have evidence to suspect that since the numbers seem good to me and my tuner. Just looking for another opinion.

$0.16 BPV Mod seems to have done it for me, at least from what I can tell so far. Hopefully that was all it was and was venting off when building boost making the turbo work out of its efficiency range and causing high temps
