Whipple diagnosis help!!

[Bharmsen]

I have had the whipple stage 2 on for about 1k miles now and just started having a surging like hesitation while driving. You can really notice it if cruise control is on just cruising. Sent Lund a log and the said their might be something restricting the MAF cause they heard a loud noise? They said throttle looked good and could be something with maf or spark plugs? Anyone have any problems like this. Goes to the shop on monday.
Thanks for any help!!

Check the plugs?

I haven't no

I'd scan for codes, check the plugs. The plugs are sensitive in these applications.

no codes, plugs look good and pulled the maf sensor and that looked good. anyone have any ideas on what else it could be besides the tune??

Did you install it yourself?
Was it ever running properly?

 

[Bharmsen]

No had a shop install. And yes was running perfect. Been on car for over 1500 miles now and just stated doing the surging/bucking 2 weeks ago.

Check all clamps and bottom of the inlet elbow to make sure nothing has come loose. Air leeks would cause issues.

did you check the gap on the plugs?
