Bad tuner?!

[lunar]

Hi so I have a supercharged (2.9l whipple) cammed pontaic g8 gt,got it back today from the shop that installed the supercharger and they use their own tuner(first red flag was he couldn't get the car to idle after trying for a whole day) keep in mind I don't have a afr sensor(planning on getting one) and I logged a few cruising and light pulls on my way back,car would show misfiring sometimes straight into kr,keep in mind I'm running methanol injection and octane booster to boost my octane to 103 octane so fuel should be a issue,ait was around 30°c and coolant was at around 88°c so air should be a problem,I noticed that bank 1 and bank 2 for short term fuel trims were waayyyy of aswell as long term fuel trims,could anyone give me some advice cuz I'm very interested to know what could be causing this,also I think the tune is running way to mutch timing in lower rpm,but then again I really don't know mutch about tuning,any help would be appreciated,I basically want to know if I'm cooked or not and if I should get a new tune asap and if this tune will hurt my engine(hasn't hone wot yet for this reason) thx for listening,I would attach the vcm scanner logs but I don't see a option to do that,also his tune is locked so I can't "fine tune" or correct it25-07-27 16-04-13.hpl25-07-27 16-13-45.hpl

We can't tell anything by a description other than its obvious you have issues.. Log and tune will help.

without tune logs or at least screen shots of the problem area, it would only be a worthless wild guess

Take it back and let him fix the tune or unlock it so you can have it fixed.
Majority of the time a locked tune is just hiding a hack job.

Sounds like you need to fix the tune. That is where I would start.

Yep, tell him to unlock it or you will have it unlocked. After it's unlocked, post it here and we can take a look.

Who can unlock the E38? Ive never tried that.

I have never used his services, so this is not an endorsement, but this guy can:

22 degrees of timing at 155 Kpa and 4000 RPM. That's freakin scary. Must be really good fuel. On 93, even with spraying some meth, you're breaking pistons.

im running 99% methanol injection and octane booster to boost my octane from 95 to 103 octane in the tank
