yeah i know matt. im on the hptuner forum lol. but i dont need help so i dont post and if someone needs help they ask.. There was a guy which i tune he made 303 whp and 427 ft lbs but his issue was the esc but also he threw a tune on the car without datalogging it and also let the car sit for 30 mins before dynoing it so it was heat soaked and it had bad plugs so he was running 13* timing and 23.5 lbs ..... i was like wtf how did you get so low of whp. (I looked at his log when he dynoed he had it had kr everywhere lol. ( the knock sensors on are cars are wierd because if you dont driv ethe car for a bit the car will just randomly throw kr everywhere and run 1 lambda till it goes into closed loop... i told him to redyno after he replaced his plugs. (and after we log some more) So im waiting ........

i think its got more... if you look at the engine RPM dyno it shows the highest torque spike is with the clutch slipping or esc finally stops and its all down from there so im thinking its got more than that. maybe not HP wise but i DEFINITELY think it has more torque to put out.
and this tune is done by a very reputable tuner who has countless tunes done and he says its perfectly safe. and +15ish hp over gms1 and mods and +65tq is definitely a large improvement as well as a possible higher tq number if you look at the graph

That 27psi is really only netting you a few ft/lbs. I made 313/388 on a dynojet with a downpipe and an 18psi e85 tune. Really not any real point in pushing your little baby snail to the limit.

i would LOVE to get a e-85 tune to push this car over the top but i nee to get the actual tuner so i dont have to drive all the way down to NC to get tuned by M-Dub

1. Definitely clutch slip. It's EXACTLY the sound and duration my car (and every other SS/TC) had when the clutch was slipping. You would not have kept making power if your tires were spinning at that low of an rpm, you don't have a huge power spike which is what causes tire spin on a dyno.
2. The clutch slip happened at low RPM and does not affect your peak HP. Your numbers are right on for a 93 tune.

Id say back it down to like 23-24 and maybe see if it can take anymore timing.

out here in VA, at all aspects motorsports. (same place as the meet last year for dyno day)
ill definitely work out the kinks, prob tune it down. still makes me smile seeing that boost gauge fly up there, but like you said if its only gaining a few hp/tq its not worth it.
still sick punching it in 2nd and 3rd and see the guy who thought he was hot **** beside me look over like he just saw a ghost

My car went from running a 14.2 (w/ GMS1 at high altitude) to running a 12.9 with just an E85 tune. And 27 PSI is not safe on this turbo unless you have had many hours tuning it at this PSI. You are supposed to work your way up to this PSI. And its still out of the turbo's efficiency range. The sweet spot is 23-24 PSI.
13 WHP is not much of an improvement over GMS1.....

Yeah, no point in pushing the turbo that hard cause at that point all your getting is really hot air and you dont even have a better IC to try and cool that back down to something the engine can use. Your better off at 23-24 with more timing. Cooler air is better than super hot compressed air, which is what you are getting at 27psi on the K04
If you understood the dynamics of it you would see why everyone is telling you that 27psi is too high for the K04, but since youre getting rid of it anyways, you probably dont care as much.

i do care, and i see what youre saying. i have an M-Dub tune so its not like i just had an average joe tune my car i had a very reputable tuner do it. who has also had more psi on his stock k04 than i do for a longer period of time.
i just recently decided to sell the car for a larger project of an LS1 since theres a bit more options with the f-body than the cobalt, and its rear wheel drive. i also always thought it would cost a ridiculous amount for insurance and i found out thats not the case so why not save money on payments and insurance to throw mods on the LS1 rather than budget more to build up a cobalt.
but thanks for the input i will look further into this and talk to my tuner and see what he says

We've broke well over 400wtq on stock clutch cars and with far less boost. The high boost tune is cool to say you have that much psi and see the look on people's faces but it really doesn't make any gains.
