Nothing negative against him, he only seems VERY **** with how he tune his car and he has a lot of people listening to what he says on here, so that kinda create the panic imo. But that can be something good sometimes (the being perfectionist part). I think that the intakes causing the most issues were not in the 3-4% range either. Hell, even if an intake would be in the 15-20% error range, but consistently there it wouldn't be much of an issue to tune.

Term2 is a trusted tuner, people take his advise seriously. And with his experience there is reason to believe him. I'm not saying I dont. Just stating a fact. But I think byt said he didnt have an issue tuning x intake while term2 did. Well you also have to take in the fact their environments, term2 in florida with WAY different weather, I'm in minnesota and byt is in cali (i think). Tunes between those states will differ. You are correct, the intakes causing issue were giving huge error ranges. Thats what I want to avoid. I am saying a proper intake should give small error ranges with in reason WITHOUT a tune. Having to tune an intake to make it work properly is great for tuner but not standard people. I dont want my gmstage 1 ecu to have to be tuned to run a intake. I think the proper intake will run small error ranges w/o tune and be a great intake to tune for. I got a 2nd pcm to tune on, I'll get hpt this summer and I'm just waiting on intakes to see how they pan out. We didnt have this much issue on intakes for the ms3 di engine. Cobb and cp-e's sri had the maf right after the filter but with a venturi and the maf wasnt a slot loading one. I wonder if the slot loading maf can cause this too? has anyone taken off the box of the maf to expose the sensor better?

lol no man, I heart term2. It is the general public here thats the issue. They take what anyone 1 person says and believe it as 100% truth with out doing their own research. I could make a post saying the lsj stock intake works way better and has 0% trim issue and people would take me seriously...maybe.

90% of this site just freaks out because their fuel trims are off a little.... honestly that is the one thing I hate about that interceptor gauge...
turn that off the car runs great, feels great.... I mean honestly a -3% LTFT isn't a make or break for your cars power...
Term is fantastic with maf tuning.... I honestly don't have the time I'll get it close and then it's good enough... most of the guys I tune are in a hurry or like Gestapo007 I just tuned his car before he got the intake so I didn't have a chance to even tune him except throw a base map HAHN maf table in it... which worked great on my car not so much on his.

If TTR would get this groupbuy in gear I'd post some datalogs to the mix, but alas....
pokepoke.
Also yes... people need to not freak out about the trims so much. The ECM (and every other modern ECM) was DESIGNED to overcome airflow/fuel trim skew. The fact is my bone stock car runs +8 /+10. Hook your scanners up to just about any vehicle and you will see they hunt around too. This was the whole point of fuel injection, it being dynamic
Now what is bad are intakes that make it impossible to get consistent tuning results, and there are a few of those out there.
Lets also not forget that many of us are running 10-15% ethanol blends which tend to have **** quality control on the blending, at least in my area, and can play into this.

To clarify my earlier comment on trims:
I'd rather have negative trims than positive because I'm running the Evap Mod, which disables LTFTs depending on how the mod is done. I'd rather be rich and it taking fuel out than lean and trying to add fuel based only off of STFTs.
