Trouble with Hypertech

[2datrl]

My otherwise stock 6.0L (2001 2500 HD) has been fitted with a K&N FIPK. This past spring I installed larger tires on an aftermarket wheel. I decided to get a Hypertech programmer for the new tire size and pick up some performance along the way.

When programmed at the 87 octane setting, I get severe pinging when I get aggressive with the throttle. With 89 octane, minor pinging with the programmer set at 87. I have not tried the 93 octane program/ gas. I called Hypertech on this. Their excuse was that I am flowing to much air with the FIPK, and that I should remove it and just use a K&N filter with the stock air box.

This sounds like a poor excuse to me, and I'd rather not dump my FIPK and then turn around and buy a new element.

I may also try to return the hypertech and try to find something better.

Right now I have returned the truck to stock tuning and all is well.

I need some help here! Thanks.

Try cleaning the mafs. Those with K&N's have had problems with the filter oil getting on the sensor wires in the mafs and causing pinging.

If you really want to make an improvement get a Wester's and sell that Hypertech!

I've never had any pinging troubles but I just have the K&N drop in not the K&N FIPK. I never run less that 93 in my truck either.Maybe go to the higher octane fuel settings and see what happens.

Did you set the 87 gas to the reformulated gas setting?

 

....and to much oil on the K&N will usually throw a code and not cause pinging

I have had the K&N FIPK and HPP3 on my 2000 5.3l for over 50K miles now.

I run 87 octane with the HPP3 set at 87 and not pinging...

 

I have read many posts where people do experience pinging but set the HPP3 higher and it goes away...

My '02 6.0 runs great with HPPIII set on 93 octane even when I run 87 gas.

No pinging.

87 octane setting on my 2002 5.3, drop-in K&N, never had any pinging of any kind.
