The lag off idle is pretty much gone. Theres a slight surge thats happening randomly now. Not able to pinpoint exactly the circumstances (its random ), so its gonna have to stay.

Ok great, thank you for letting me know on that one

Thanks for supporting the CTS-V. I am considering buying a Trinity. I currently have a CAI installed, and have a 2.55 upper pulley waiting to be installed. Will the 91 octane tune be safe for this application? Also, the car is an automatic. I understand it will tune the TCM as well. Does it leave enough TM in the transmission to be safe? Thanks.

yes, yes, and yes

The 91 tune will work great with your current set up, then swap to the pulley tune once you up the boost.

TM is not removed, just reduced

Mike, Are you gonna fix the dashboard or should I mess with it myself?

Terrific Mike. Thanks. Just ordered one. How robust is the data logging feature? And is the Trinity set-up to recognize knock retard in case I need to tone things down? I imagine the initial tune is pretty conservative. I live in a hot climate, well above sea level and have 91 octane to boot.

You can see anything you need.

There is a knock pid, and you can see actual timing, commanded timing, commanded AFR, boost, inj pw, and more

The tunes are conservative for sure.

Terrific. I look forward to learning the unit.

Spoke too soon. When the car is cold the lag is still there, and it bangs into gear. 43Â°. Lagged, then it short shifted into 2nd HARD.

See if you can get a log of that...its gonna be a while before we see 43*

It hasn't been getting that cold here either. Next time it does I'll get the log.

Hey I was just wondering if the stock injectors could handle 15psi. I am about to put on a 9.1 lower pully to run with my 2.5 upper pulley. So im going to be right at 15psi. I have 80# injectors on hand to put in, but if I do can someone make a base tune for me so I can dial it in myself?

Put it on and then log the IPW to see if they're maxxing out.

You have a bigger heat exchanger, right? Otherwise thats too much boost and you'll heatsoak, get knock and lose power.

Ok I have not logged ipw but my idc was at 110% at only 12.75 psi. Which leads me to belive the stockers could not handle another 2 psi.

Your injector has completely maxed out and only ran 100%, you just ran it past its operating range... It is impossible to physically run an injector HIGHER than 100%.

so yeah, if your duty cycle is reading 110%, you need bigger injectors man... generally, you don't want the duty cycle to be more than 80-85%....

Ok thats what I was thinking. I will go ahead and put these in next week. Would it be posible to get the pulley tune scaled back for my 80# injectors. Is it something I could do or would have to get done. There is really not a good gm cmr tuner close to me.
