i trust my tuner 100%
when i get the 100mm MAF i'll get the saxonpc honeycomb airflow straightener to help smoothing the air flow
is the above dyno graph is from 347/367 ci?
i agree something wrong with my setup, but i just can't figure out how after the FAST 102 my car did not run lean at all, and the AFR stays the same

not sure of engine size, but it wasnt anything crazy..
and you may trust your tuner...but with a result like that... I would second guess him and at least ask for a copy of the tune that you could email somebody like myself for a second opinion to see if theres anything obvious that looks like the culprit

Don't waste your money on a 100mm maf.. Go put it on Abel's Dynojet & watch your #'s go up to the 430-450 range.. An even better idea would be to go to the track tmrw & see what it mph's. There's not a whole bunch you can do to a wot tune. Your's was at 28* timing with a 12.5-12.7 afr with no knock.

no knock does not mean best timing....
I've seen a lot of cars with timing at 28 and when backed down to 26 piked up quite a bit of power
also, 12.5-12.7 may be a bit rich...not saying it is...Just consider that theres power to be made if you play with the fueling as well
a flat 28* would be incorrect...
the LS1 likes a little dip in the timing around peak torque....not that its going to change the #'s up top..but it will change the #'s in the mid range
I agree with the track comment...
see what MPH it traps and that should give you a good indication..
also... meter your Voltage (or just log it in your scanner) and see what its doing...
I've seen a lot of cars(my own included) that had pretty good voltage drops as rpm went up...which cost power.
solutions include a higher output alternator, and better wiring(usually the Big3)

The dyno jet graph in the thread is from abel racing, I made 438.
I'm not upset about the peak hp, but rather I lost power between 3000rpm all the way up to 5900rpm, I may go to the track tomorrow to see what she does.

why is everyone comparing a fast 92 setup to his fast 102 setup? did i miss something here? ive heard time and time again that you will not benefit from a 102 unless you are over 400ci hence why i have not done it yet but want to.

I think if he's really caught up in the dyno #'s, he should put it on a dyno-jet & see if it picks up everywhere vs the mustang dyno.

If I swap to 100mm maf, what do you guys think will be the downfall to that? The fact that's. Its losing power anywhere across the board is what caught me not the peak number.
I messaged glen and I think he got a little bit pissed by me with me asking for the copy of the tune since he's busy, now I feel bad

I dont care what somebody's reputation is...if they are a good tuner, they will let you have the file without being upset about it...
Tuning is not like its a one of a kind top secret voodoo any more like when people first started doing it.
either you are doing it correct, or you are not

Why are you set on buying a 100mm maf? That's a waste of money & will you gain you lil if anything at all. My old H/C setup only made 385 to the rear wheels on a dyno jet, but trapped 115 in the 1/4 at full weight.. Going by a calculator that's more like 420 to the wheels.. Take your car to the track before you start wasting money on unnecessary mods.

In His case.. the 102 should be better than his ls6...and the 102tb should be better than his previous as well
again.... on a 346 ci engine(or any LSx engine), I've never seen a car lose power from swapping up to a 102 intake/tb combo
and I have tuned probably close to 20 of them now(maybe not as much as some people...but its more than enough to show that it works every time)

MM are you mike miller that glen called yesterday? I figure I can always sell it because my friend is building a stroker lq9 427 along with the 104 lid. I'll use this moment as an apple to apple comparison between my MAF and lid that I have right now with bigger one.
I'll take pic of the lid and MAF that I have right now, it's granatelli and it should be stocker size, but when I took a measurement today it was actually 90mm..and the lid is matching it.
I will still take it to the track, but the fact that lose power everywhere except for the peak on the same dyno and similar weather really bug me

Sound: in glen's defense I'd be pissed off too if my customer brought the car to me and have me tuned it and turn around and asking for the tune file because he/she thought that the problem is in the tune.
He's a very nice and stand up guy, he didn't even charge me anything when he looked up the tune.
