Lack in Driveability with Whipple Stage 2

Hi guys,

Hope everyone doing well!

With custom dyno tune and Whipple stage 2 (132mm billit is in) I am still having issues with driveability.

Such as:

1- Lag when my leg is off the pedal then try to accelerate while everything return to be okay when I press the clutch and release it.
2- Idle still not OK. I am doing 850-950rpm.

If it could be tuning issues, any solution have been experienced?

Someone said: with WOT box you will be fine.

Any advice or experience?

Who tuned it sounds like running issue
I have stage 2 as well
Car drives like stock

Do you have your airbox lid on? I've noticed without it, I get a lot of lag in RPM drop. Also, Ken B or Lund, get them to tune your car. No one else. Or go back to Whipple's tune

Since you are in Saudi Arabia you should prob try and find a tuner who knows how to tune coyotes, MAS Tuning should be able to get you taken care of. They know their stuff and have tuned a ton of coyotes

It sounds crazy but, make sure the couplings from the TB to the air box are all the way over the tube and TB.. Check all vacuum lines also I had this happen and my car drove awful.. Did a once over and found the problem.. Sometimes the answer is so simple you never think to check it.

Change my tuner to be Ken B from PBD and:

Everything got fixed after the initial start up file!!

The car drives like a stock but with extra +250whp.

Thank you [MENTION=10794]KenB[/MENTION] for awesome tune and service.

Good deal. Enjoy!
