Stock 93 octane tune overboosting on stock 2005 srt 4
Hello guys im new to the forums i have 2005 srt 4 fully stock just a mopar bov plate. I bought an intune i2010 for my srt 4 but for some reason when i install the 93 octane tune it will overboost in 3-4 i hit 21-22psi almost all the way to redline im in florida so the weather is hot here about 88 degrees. I have checked for leaks i have reset the pcm and reinstalled my intune i did the update before installing any map in the car. I wanted to know someone can take a look at the last written tune i have to see if they see something off. Please help!!

Ok well here is what i did i used the advance tune option and used the diablo tune and modifyed the boost. I took away 3% of boost in 1-2 took away boost in all other gears. I took 15% from 2-5 and it seemed to work now boosting at about 16psi from 2-5 with a spike around 17.5-18 but will drop back down to 16psi. I no longer see 22psi or even 20psi. I will post logs to see how you think the tune looks.

Trust me. Get a different tuner. Incase you haven't seen my post go look at them. His exact reply was is everything stock and are all vac lines ran correctly or whatever. Ummm yes. Technician at Mopar installed everything so........ Just trying to save you some money because the 93 tune made my car spike to like 22lbs and also go lean so needless to say I had to get a motor and turbo because of the 93 tune. The stock turbos are only good for around 18lbs when you go to 20 and 22 it starts chewing stuff up and spitting it in the motor. Much less running a turbo car lean..... valves, pistons, head damage, cylinder walls etc etc
