I am very picky with the way my car runs, It wasn't as fast on low RPMs before but it was SMOOTHER. I am taking out the chip to see if it makes a difference. Has anyone had a similar experience? |
Definitely check with Michael (LAN) to make sure you did everything right during the install. You kept yourself grounded while removing the stock chip and installing the ECUTune chip, right?
Are you saying that the engine is turning at 3,000 rpms while you're cruising at 40mph? Is so, you should probably have another look at the trans.
Can you get the car to a shop that has a diagnostic machine with an A/F probe?
