My '07 350 didn't either. I can't imagine that it's by design but probably a by-product of something else.

Well, it certainly doesn't feel natural. If there wasn't an initial surge of power I would attribute it to just a lack of low-end torque, but since we get that surge followed by an immediate loss in power it has to be something else.

Agreed! Very "artificial" feeling, as DIGI stated.

Im assuming that car is tuned as well? If not, how did he get the car to rev out that far?

RedBullRR · 12-29-2010, 09:47 AM

I've heard a UPREV tune can remove that, is it designed in the ECU Mapping?

m4a1mustang · 12-29-2010, 09:51 AM

Any of the tuners can modify the rev limit. Whether he has a tune or he just bumped up the limiter we won't know unless we ask.

It's been a day and a half since I changed my K&N air filters to "stock" (I purchased the cheapest air filters from NAPA). I have not experienced the lag issue yet! I haven't driven a whole lot either though. I'll update again in a couple days. If it's something that simple, I'll be very happy but irked.

m4a1mustang · 12-29-2010, 10:29 AM

Did you by any chance reset the ECU when you did the filter change?

I noticed whenever I reset the ECU the car would feel good for a little while before reverting back to the same BS.

I thought about it, but didn't ultimately.

Update: I just ran some errands during lunch, and I did experience it again. It didn't seem AS bad as sometimes. Could be just hopeful thinking, or the combination that it was just starting on the last stretch of my drive. I would say air filters are NOT the problem (as guessed earlier by others).

I'm not sure if you see this info on technosquare, <TECHNOSQUARE - ECU FAQ>

Wow, very interesting... and exciting.

I have heard good things about technosquare.

This is a better set up to change the lag problem. once your pedal it precise and has no delay then i would go messin around under the engine. When I get my Z in July im getting this FOR SURE
