I'm installing rip a tune sleeve and already have 2.85 upper with stock tensioner . Is anyone running this setup and can help a guy out with belt size?I know I can buy the adjustable tensioner but would rather save the money abd just get the correct belt size. Thanks

I currently have a 2.85 upper & Ripatuned Incognito lower with stock tensioner. I have the Gates K100594HD green belt. No issues or slipping so far.
well I'll be damn someone is running the same set up......that also the belt I have so when I install the sleeve maybe everything will be good. I buy it used and hasnt come yet just trying have some idea what to expect. Thanks
I run only 93 I dont think I have enough injector for e-85....but with the 2.85 and incognito I'm seeing 17lbs. and I also use vp unleaded additive.

I'm going to have to get mine tuned again also...for some reason it seems to be running rich
I have also heard that but knowing it for fact I dont and I also dont believe everything I read on the internet....lol But I do know that at around 5300rpm mine's is bleeding off boost for some reason.I can see it on the logs but cant find the reason yet.

that I'm not sure of but when Demon Performance tunes it I'll know....It might have something to with the bypass valve's releasing boost when it's to much for the engine.Just dont know that the reason I'm having it retuned.But I think your right it releasing boost for safety trying to protect the engine

In looking over one of your logs your injector duty cycle is hitting 85%, at 90% the PCM will open the bypass valve to bleed boost. Be VERY careful with boost over 17 psi on 93. You logs also show STKR and the tune looks like it can reach 14 degrees if timing. 14 degrees of timing and 17+ lbs of boost = detonation on 93 no doubt. The VP Octanium Unleaded will get your octane up high enough for 14+17-18 but continued and constant use of it at the level needed, 1 Qt in 15 gallons is going to do a number on your exhaust valves and seats. I know from 2 years of doing such what it nets. If E85 is right close to you get on it ASAP before you hurt your engine to where it has to come out for repair. It only takes one bad detonation event to ruin ring sealing then increasing blow by compounds itself afterwards to a catostophic event.
Mike I do have e-85 close to me and would run e-85 but I would have to change out the Injectors correct?And I'm going to e-85 I would need to be tuned for it.
I'm just throwing this out there...I wonder in my logs would the reset all adaptive's keep the fuel trims from being normal or would they should be it the car isn't driven long enough?I always reset after doing any change in tune.And just a short drive down the road might not be enough time?
