So I just got a AP v3 yesterday and installed the stage 1 aggressive map. I'm basically stock besides dci and running 93 oct. And wow it's a HUGEEE difference ...
but for some reason when WOT or under a lot of load the engine seems to stumble or "try to catch up with itself", but does not feel like a misfire. I was having misfires recently so I changed spark plugs around 200 miles ago. Could this map be too agressive for me?

There's a decent chance the dirty intake valves are causing the hesitation then.

What's a fair or average price to pay for walnut blasting on the intake?

I'm actually going to be getting mine done this summer. The stealership charges around $700, indy maybe $5-600 but there's a guy from N54 tech that does them near me for like $300 I believe.

There's also plenty of Indy shops that do it for $300-400.

Valve cleaning prices vary by location . I just had mine done for 400$ and they were gunked up at 47k .

Good to know. Thanks.

Look into replacing the coil packs as well. Worth it for under $200 for all 6.

Hmm I do have some coils laying around but I just replaced 3 coils around 8k miles ago. Does it matter if the coils are all the same brand?
Man looks like i'll have to look into getting my intake valves cleaned soon T__T

If you had to replace a few already, the others aren't far behind. It's one of those things you do all at once if one or more are giving issues.

Tuned cars chew through plugs and coils at much shorter maintenance intervals.

You need to pull the codes and post a datalog

I will try to post them asap after work! Also,
Also, noob question but when I go to cobbtuning to download maps, i see maps for ecu: IF80S, or IKB0S, etc... what are these codes and do they matter?

^ Is that "code" just the ecu version?? so I would have to get a map for the ecu version?

correct this is the ecu version. You need to download the correct one for your ecu

[HooDat]

So here i finally got to do the datalog and car threw no codes:

Is that log at WOT? The middle of the log looks like you lift your foot off the pedal.

[HooDat]

yeah should be WOT, i started around 2.5k rpm and had 1/4 throttle and then eased my way to WOT and probably stopped a little before 6k rpm.
I uploaded another log too, but not sure if this was any better:

This one looks better, but i'm not a great datalog reader so i'd wait for someone a bit more experienced on Cobb logs chime in.

But, the first log you posted has a huge dip in the middle where pedal position goes from 99.6% to like 50%, which would be like if you lifted off mid-log. Boost, and a few other factors all look like they reacted as well.

ah okay! yeah i may do some more logs later if these aren't good enough. Thanks for chiming in though.

Any input from the pros?
