yes, any gear slip is a symptom of a failing clutch, I get that.
My point is it is totally unclear what is actually happening here.
Everybody keeps repeating "talk to your tuner" despite that being pointless if he is giving his tuner the same sketchy information we are getting.
It will just be a wild goose chase

Yes in post #14 I was referring to rpm spike, what happened was I was in 5th on the highway doing 80 right around 3k had to get in the other lane to hit my exit. Stepped on the the rpms went smooth from 3k-3.2k then blipped up to 3.6k and right back down to 3.2k and kept accelerating after. The car didnít jolt or jerk or hesitate the rpms just spiked. It did like almost 5 times same speed and gear but only did it when I was using the pro tune from ia tuning. Didnít do it when I was using the cobb ots tune.

Do you know what the boost is showing at those rpm points on both tunes ? Do a log on the Cobb tune and then on the other tune and see if the boost is the same at those point in the rpm range

Your clutch is slipping. It probably only does it on the pro tune because the pro tune is making more torque, which your clutch can't handle. How many miles on the clutch? Is it a stock or aftermarket clutch? If aftermarket, which one?

If you want to run the pro tune, replace/upgrade your clutch
If you don't want to replace/upgrade your clutch, run the other tune

In either case, plan for replacing your clutch in the not too distant future. Sounds like its due.

I believe itís a stock clutch. So 98k miles

There you go. At 98k miles on a stock clutch you're at the end of its life. Look for a new clutch that will handle the torque your pro tune can put out and get that installed. A new stuck clutch might not cut it if so do your research.

The only thing your tuner could possibly do to "fix" this is dial back your tune to produce less power so the clutch doesn't slip.

Good luck!

Clutch is a wear item, don't be surprised when it starts slipping with the other tune. Not a question of if, but when.

Save your pennies, get the clutch done, break it in properly, then load up the pro tune and let 'er rip!

Unless your going over 100mph already you shouldnt be boosting 5th or 6th. Downshift your car

98k isn't even close to the end of a clutch life if it isn't abused

^Whaaaaaat??????
100mph in 6th gear turns 4000 rpm's
5th is probably 5000

boy oh boy the lugging nonsense.
He should be able to hit boost at any rpm the engine runs ok at, which in the case of these cars is 2000+
Obviously it isn't going to pull hard at 2000 but boost whatever you want

I go WOT in 6th uphill every day from 2500 to whatever, no matter how long it takes.
113,000 miles and it runs like new.

For gods sake why do people think you can't use the turbo in certain gears.
I think people say this cause people try floor it and lug down the engine at 2000 trying to get the engine to make power

yeah, and bottom line is at 2000 rpm's it won't build but maybe 5psi of boost anyway. It won't hurt anything but it won't accelerate for crap from that rpm other than 1st through maybe 3rd
