hptuners timing problem. dyno sheet posted
The car is stupid rich down low, but I don't want to pull fuel on a tune I know nothing about without a wideband. I cranked the timing up a bit and got more power out of it once it's spooled, and a little better spool up, but thats all. Needs fuel tuning for sure.
Im going to try replacing the intake / exhaust gasket...
Ive noticed some carbon build up on the right side of my intake manfold (on the block)...
Im just changing the exhaust gaskets because i think it may be necessary.
Cant wait for this wideband to show up

More than that. Did you ever actually have that tune?
I wanna say it was in the 16-17 range, but it was a while back, I don't recall off the top of my head.
Also, keep in mind, every car is different. Find what works well on your car and makes the most power safely and be happy. Don't look at timing numbers on someone else's car and feel like you aren't doing as well, your car may make more power on 18 degress of timing than someone else is on 20.

Exhaust might cause the spool issues, but the car idles too smooth to have an intake leak from what I saw. Can't hurt though.

im on 7gph @ 10+psi and honestly i can only get away with 14-15 on high boost, and about 16-17 on 15psi
i thought i could go more but it knocks around 4500-5000 when the trq and boost come on hard. then i can slowly ramp it up to 17-18 but the midrange were the turbo shines it doesent like timing.
1 step colder plugs
160 thermo
91oct + 95% meth @ 7gph
if you have 93 then i would say 2 degrees more maybe.
just so you know what to expect
but like joe said its not about the numbers its about what is safe and what that car likes/wants

The downside is, it's really hot and humid all the time, so IAT can be 10 degress higher than what a lot of people are used to seeing.
I can only run that kind of low timing as well. I think it has to do with the plugs being to hot. I'm not 100% but I have bkr8e's as per recommendation of Paul coming. I'll see if that does anything.
i just chalk it up to the shitty gas and i dont worry to much about timing i just add boost if im looking for more powa
but im built so i can rely on boost to make my power and then also that way im not always on the verge of knocking trying to squeeze out 5whp or something.
i have tried
bkr7e
bkr8eix
bkr6e (stock)
3922
gaps:
.28-.36
and have never seen any difference between the two besides the misfires at idle with the bkr8eix
i gave up on plugs along time ago. i stick with one step colder and .32 gap

I figure I will try them even if they don't work I will never be wondering. With racegas I can get way up there into the 25 area. I would assume that because I'm already running meth that it wouldn't increase too much but apparently the meth isn't as effective as I had hoped.
I'm going to try a preturbo injection setup. AIS highly recommended it I'll see if that lets me be more aggressive with the timing.

my iat's never get high ever and i think he is thinking were running a little turbo and maxxing it out, but i could be wrong... he kept trying to tell me about iat's in the 140' and 150's
ever since the swap i have never seen iat-2's above 120 ever.... and with the meth they are usually 10-20 degrees lower than ambient.... and i live in the socal desert.
but if you do try that i would like to see/hear of your results...
i just thought of this, why not tee off the pump line and spray pre turbo and post turbo? i say like 3gph pre turbo and 5gph at the TB
