Had my car tuned yesterday. Results.

Here is most of what I can think of what is done to my car
CX racing FMIC
CX racing hard radiator pipes
HKS BOV
Polished plenum, valve covers, throttle body, etc
3rd gen lifters
Fuelab FPR with STM fuel pressure gauge
Made my own fuel lines as well as filter
550cc precision injectors
Fidanza Aluminum flywheel
Spec 3+ clutch
Tanabe knockoff exhaust with 3" downpipe
19T turbos
2 core radiator with slim fans
Battery relocation
Wiring tuck
Moved fuse box and AC box
Urethane motor mounts
Brian Crower Rods
Weisco Pistons with harden wrist pins
High Rev Springs
Forged Crank
AEM EMS with map sensor and IAT sensor (mounted about 6-8 inches away from TB)

The highest we went was 363awhp on a mustang dyno and backed off a little
the charged temps we 130+
I am not discrediting the place I got it tuned from by any means because I know they know their shit, 363 seems a little low for my set up and basing off what other members have said I should make around, I am nearly 100 off of what people have said. They said I need a new core to help cool my temps while I have talked to chris hill and many others and they are all running the same core and not having problems. I am going to be moving the battery back under the hood but wondering what every ones thoughts would be on this. I plan on switching to e85 but id personally rather not just because they are not many pumps around me with it.

How much boost?

Was it tuned at a place that does alot of Evo's and GTR's and shares the same amount of letters in their name as the name of the cars I just mentioned?

Any reason for not taking it to Pampena?(other than distance?)

keep in mind mustang dyno's seem to read low. Was this on straight pump gas and if so what boost pressure?

it just touched 19psi at 363 on straight pump gas. Right on with the name jbuhrman, i know mustang dynos tend to read low so i was expecting it to lower but not this much lower. distance and my car was running like crap on the SAFC i had. right now i am hitting between 17-18psi and dropped down to about 350awhp. the car probably had heat soak would be my guess.

not to sound dumb, but why was 363awhp the highest you went? did the dyno tuner start to see pre-detonation and then backed your boost down to a safe level? Im pretty sure there was a guy in MA who was around 390-400 awhp on 13g's so i would def say that youre 19T's have a lot left in them.

Maybe another member with an IAT sensor can chime in but 130* F doesnt sound high. I might be way off by saying that but i know for a fact that after a pull my IC pipes are hot enough that they will burn your hands and if water touches the pipes it will turn to steam within a few seconds...

he was getting knock, but didnt know if it was just engine noise or actual knock. pulled the front plugs and there was no sign of it at all. he just didnt want to go any higher because of the charged temps, and i dont really know too much about the tuning aspect or charged temps so thats why i hope to find some help with this. i have a couple things i half assed on with the wiring but thats minor and i know it didnt affect it, so i plan on fixing all of that. he didnt really do any type of cool down periods for about 5 hours so it clearly gets really hot just sitting there on a dyno.

How new is the knock sensor?

I don't think 130* is "that" hot but its alittle up there. Also people have made more power on the cx stuff before unless you got a really craptastic one...

knock sensor looks like the original one lol. chris hill runs the cx racing one in his and makes 835 so it cant be the core, plus from what i have researched, people have made more with just the stock side mounts.

Must be a super conservative tune. Mustang dyno or not, those numbers are very low. Those guys should know that these engines are inherently noisy; the valve train makes a lot of racket.

They tuned Austin's stealth(STM) so shouldn't be an issue with that

Yeah, but, a 9b car running E85 is pretty forgiving. I'd find a way to get it to Ray. Well worth the money spent.

Problems I have...
AFRs under boost starting around 2500-3000 go to 10 and it hesitates pretty hard.
When coming to a stop and putting the car in neutral, it will either surge and stall or surge and finally smooth itself out.
Cold starts are fine, warm starts it will normally stall out.
When just cruising, going from a decel to pressing the gas lightly it will lean out for about 3-5 secs, hesitate and then finally cruise normal and back up to the right AFRs

360 on a mustang dyno comes out close to 390ish on a dynojet...On my stock SMIC's and pumpgas I wasn't able to go over 400whp dynojet (385whp) without seeing knock...so you're in the right ballpark. Thuanvinny got his car tuned by Pampena and made a safe 410whp(dynojet) on pump and 19T's. TwIzTeD is near 400whp on pump right now too...so you're not too far off..with e85 and more boost/timing you will easily pick up close to another 80-100whp no problem.

If you've got stalling surging issues...check for boost leaks...they can affect the tune HUGELY...

isnt twisted around 442 between 19-20psi being heatsoaked? thats what i read from his post. at 18psi 350 is very low at that psi from what i have been told by people, from what i have also read on many posts is that these turbos are plenty capable of 450 on pump and 600 on e85. correct me if i am wrong please. i never had surging issues until after the tune, i did a boost leak test about a month or so ago and found nothing, i am doing and smoke leak check this weekend to double check it.

He made 450 with a super rich AFR and lots of boost.

He made low 400's with a more proper tune(11's AFR) and less boost due to knock.
