2011 WRX - Stage 1 Boost (Logs Included)
I recently flashed my 2011 WRX to Stage 1 91 MTv331. My car has the SPT catback exhaust, but is otherwise stock, and I consistently use 92 octane.
I've collected a few logs and don't appear to be hitting boost target (~16.5 psi for this map). TD Boost Error is well over 1 for most of a 100% throttle 3rd gear pull. DAM and knock metrics seem OK based on my limited understanding. Conditions during the logs were ~65 degrees and low elevation (~1-300 feet). https://1drv.ms/f/s!ArDhad7AwPCoz9YnmNkSzsVyj2Y3tg Any input on these logs would be appreciated. Logs 6 and 7 are probably most useful - they include full 3rd gear 100% throttle pulls. The rest are a mix of 3rd and a couple 4th gear pulls, but not to redline. Do I have an issue? Should I try the HWG map? I have a similar email out to Cobb but haven't heard back yet... I have some time this weekend to tinker if needed, so any advice would help. Thanks!

I added a few more logs (datalog10-12) at the same link. They're 3rd gear pulls at 100% throttle. I wasn't able to hit redline, but should have been able to hit near boost target. TD Boost Error is 2 to 3 when it should be peaking. Any suggestions?

Go to the torqued performance website. I got a AP V3 and loaded in cobbs stage 1 91 oct map and was stuck at 15psi as well. Was kinda disappointed. Found out about TP and bought his accessport stage 1 91oct map for $99. Immediately i was hitting an 18psi target with peaks of 19psi. He also e-tuned me 7 revisions to get me running great. All for the $99 i paid for the map. As per the 8psi? You must have been running an eco map.

Forget the last sentence. About the 8psi

Send the full pull to cobb. They will tell you.

Cobb replied (quoted below). I知 surprised my concern with TD Boost Error wasn稚 even mentioned. Am I over-thinking this?
Do barometric compensation and intake air temp even matter when evaluating TD Boost Error? My understanding is it compares target boost (which could be modified by ECU) with actual boost, and the value should remain +/- 1 (regardless of ECU intervention). My logs are way outside this, and I知 more concerned with boost error and delivery than peak PSI. I値l try the HWG map and see how it goes... Quote:

the maps are conservative for a reason, they are generic tunes made for 1,000's of different cars to run. try the hwg map see if it helps. you can also try a helper spring on the WG if that's your issue.
if you're concenred if it's tune or mechanical, reset the ECU and do a pull. if you now hit target boost then it's the tune/your ecu lowering boost. if you reset and it's still not close, or it's exactly the same as it was then it's most likely something mechanical. make sure all of your boost hoses are installed and in good condition, check intercooler and bov connections etc. |

Thanks hondaeater. These are the kind of suggestions I've been looking for from Cobb. Very helpful for someone new to AP and tuning.
Cobb's last response to me is below. Seems like they're avoiding the issue by making overly generic statements. Boost error is well outside their recommended +/- 1 spec when I should be making good boost (~3k-5k WOT). Is this what I should expect from them? Seemed like people have been happy with their support, but I've been underwhelmed so far. Quote:

they suggested trying their HWG map, did you?

Haven't had the chance to log yet, so no. I joined the "I sheared the turbo --> IC bolt" club and need time to drill that sucker out.
It does look like I had the IC --> TB hose issue which may have been leaking boost. Connection at TB was questionable and, once removed, it looked just like pics and vids I've seen around. Hoping to get things back together soon, securely, and logging then to see how it goes. |

I've ran the stage 2 TP map for months never had 1 single problem. Eric knows his ****. Download his map, run your logs and send to him. He will look them over and adjust to your car. Make sure you let him know everything about the car. Mods, intentions, driving style, everything. He will continue to readjustas needed. He is fast at adjustments too, I sent him logs once at 3pm and got a new map to run at 5pm. If money is an issue then don't tune. 99bucks is nothing compared to the money your gonna spend if you decide to go stage 2 or above. Let alone the rest of the car. I look at it as a $99 assurance that it will run right. It's cheaper than a new block believe me been there...

What if $99 is a big deal - should I give up and sell my AP to some kid with rich parents? Why should I do anything other than confirm and fix potential mechanical issues first? What if I would be happy with a Cobb OTS map? Tell me again why I should pay TP for a map that I don't want at this point? Reality is $99 isn't the problem. Addressing potential mechanical issues is my priority. If I go stage 2 + (unlikely in this car), I would pro tune. |

Your comment on not asking for "tuning" advice before I address mechanical issues makes no sense in this context. I agree if the issue is known. The AP datalog is precisely what led me to suspect a mechanical issue. I then took action to investigate and fix it. |

I fixed the sheared turbo --> IC bolt by drilling through it with progressively larger bits, then re-tapping the threads. It took time, but wasn't as bad as I'd expected.
I reassembled everything properly and I'm building boost earlier which is nice. I'm also peaking just over 16 PSI on some logs. I do think the TB connection was leaking. I'm still not quite at target boost, even with the HWG map. TD Boost Error is still over 1 through most of a WOT pull, but it's not as bad as before. My plan is to keep an eye on things with the HWG map and see how it goes. This might be as good as it gets with the current OTS map. |

Check your turbo inlet pipe and clamps they are prone to failure. Also ive had the same problem with the IC bolt. I did some searching and found that using a thick waterneck gasket for a sbc fits the IC to Turbo connection with slight timing works wonders to seal as apposed to just the rubber gasket. To follow up on your last, I was only stating that if you were having issues with what you thought was the tune, to try another one (tp) which has been far better for a lot of people then Cobbs standard ots. That was prior to knowing you had other possible issues. Goodluck

Are Cobb tunes really as bad as a lot of people make them out to be?

I have another email out to Cobb hoping for suggestions, but I suspect it may be as good as it gets with the current map (and from their support). It'd be a shame since their map notes and +/- 1 TD Boost Error target indicate I知 not where I should be:
