How unsafe is my new tune?

Got tuned by someone local the other night and did some logs today. Car is a stock block Evo IX with CBRD BBK Full, GSC S2s, and pretty much every supporting mod. I asked for 28-30 psi max and that's what my AEM TruBoost was showing that night. This is on 93 octane and in 3rd gear.

Problem is the TruBoost can only display 29.5 psi max unless you get the additional sensor to display up to 50 psi. Good thing I just installed an OMNI 4bar map sensor to log boost. Either my tuner didn't know that or he wasn't logging boost at all because apparently I'm spiking 36 psi!? I should say that I'm almost positive I set up the OMNI right but any help in that regard is appreciated.

The area in red especially has me concerned. I'm new to tuning but I'm pretty sure 35 psi on 93 octane with AFR's in the high 12s is just begging for trouble. Am I right in thinking this is far from a safe tune? Should I be pissed? I'm starting to think so. The only positive is I don't seem to be knocking anywhere. Be brutally honest guys. I can take it.



And the Virtual Dyno. Torque is impressive I guess, but the AFR curve sure doesn't seem to be. Also I know the car should be making more power up top but it was knocking like crazy so the timing isn't very aggressive up there. I'm more concerned with keeping my motor from blowing apart when the BBK spools at the moment.

pretty horrible. get yourself a programmer and pm me and i can fix it for cheap (i have programmers in stock also). also to little timing with high boost will skyrocket the EGT's and can be very unhealthy for the engine as well.

12.7-12.8 AFR at peak boost is certainly not ok. looks like a sloppy quick tune to me.

With AFRs like that yes you should be pissed.

I highly doubt you at 36 psi as your load is only 212. unless you have something setup wrong there I doubt its 36 psi. the afrs do get a good bit lean though no matter what the case. Put a actual boost gauge on it and see what the boost really is.

OP you're logging load calculated. If you're on tephra v7 use 1 byte or setup the 2 byte in the MUT table. That will help everyone help you. Also post up knock voltage.

Load calculated is not the same thing as load 1byte and 2byte. If the 4bar map sensor says its running 36psi its running 36psi.. the only way it can be inaccurate is if the Eval in evoscan is setup improperly which i highly doubt based on the torque curve of the car on 93oct and what the log is displaying and the timing.

Open your evoscan and read how Load Calculated actually works. ( I believe if you have the "injector scaling" in evoscan set to default 513 it will screw it all up since it uses that during its calculation..

also look at the WGDC in the log. this cars way over 30psi at peak boost.

3* at 6k?

You EGT must be through the roof. AFR and boost is also totally wreckless if it's accurate.

Stop going WOT and get a proper tune or tune it yourself.

You sig says "earth" so it's hard to make a proper reccomendation of who is closest to you locally---- Please get this car in the hands of a reputable tuner.

The map looks ok but since we don't know what load you're hitting yet it's hard to tell whether it's safe or not.

its using 300 to 320 you can tell by his log. cars most likely going off the map at peak boost, so needs more resolution in the load scaling. probably air temp trim tables screwing with the timing also.. just a crap tune in general.

Worst tune, if you want to even call it that, I've seen in a while. Please demand your money back and find a reputable tuner.
