Anyone else have whipple cal surging and hesitation issues?

[HoustonGT]

I have a 2020 PP2 car and just got a gen 5 whipple stage 2 kit installed. I am experiencing some very strong surging/bucking once in a while. Plus, when cruising at lower rpm's (2,500 to 3,500'ish) it feels like the fuel is cutting out and in which causes a hesitation. The shop that did the install is a certified whipple installer and has done dozens of SC installs, so I am assuming it's the cal and not the install that is causing issues. Anyone else have similar issues.?

I'll create a customer service ticket with whipple to see if we can get it figured out...

I have 1200ish miles on my Whipple stage 2 cal in my 2017 car. Never noticed any strong surging or bucking. I will say every now and then at that 2500-3500 range if you suddenly get moderately on the throttle, the acceleration doesn’t feel as smooth. No one riding in the car would ever notice it, but as the driver I feel the very slightest of hesitation at times. I just assumed it was the bypass valve in the blower getting confused with my throttle modulation.

If it’s predictable and repeatable, log it and send it to Whipple. I’m sure they’ll help get you squared aware.

I also went with a shop that did a bunch of sc installs and are a roush certified installer
I’ve been having a bunch of issues surging and bucking being two of them. I’ve been chasing problems for months. I was thinking maybe throttle body, bypass, or even tuning related.Well today I was swapping injectors and tuners(Lund now) and I had to take apart the sc to do so. And I noticed the shop never installed the intake manifold gaskets. I’m currently waiting for gaskets hopefully this fixes my problems.

I made a post that shows a picture if your interested in seeing it.

Interesting...sending a data log to whipple to see what they say. Shop is willing to take a look at it as well. Thanks for the input.

Try cleaning the valves and throttle body. I had the same issue, and this did it for me

I should have added that the SC was installed a week ago and has had the issues from the start.

Whipple calibration doesn’t have surging.

you need to log it and start to look for your issue

I have had a lot of procharger cars have this same issue. Normally it is in the throttle body data

I have it with my 2017 with a Gen 5 stage 2 Whipple. It doesn't happen very often (maybe once or twice a week?). I have started to notice that it does the surging/bucking when I start it up and take off right away. However, if I start it up and let the rpms idle back down and stabilize then I don't get the surging.

I have had the same issue since my sc was installed. Never been able to get it to quite. mine sounds the same as yours, low rpms, usually when cruising in town. Mine is a gen 5 stage 2, did it from day 1 with a brand new throttle body. let me know if you can figure this out.

You have a 2018+? Manual or auto? Yep, happens most often when cruising in town at low rpm's maintaining a constant speed...

 

[TimT]

I have an 18 with a manual, stage 2. Sorry it took me so long to reply.

Kinda feels like you are dragging on the brake, even does it with cruise control set around 40 mph.

Was out of town for a week. Just sent data log file a couple of days ago. Will update when I hear back from them...
