Throttle Response ?

[Greenhornet2]

I would lean more towards making sure you don't have a poor seal allowing unmetered air in somewhere. That will cause many issues. With a correct install and it being the only mod, it will not affect throttle response and wouldn't need to be tuned.

Yes that is true, but I was thinking that maybe disconnecting the battery for overnight and hooking it back up would reset the ECU program from whatever it wasn't doing correctly. Just a thought..

Maybe spooling is not the correct term . There is a definite time lapse between my foot pushing to WOT and reaction by the engine . Is it possible the MAF sensor causes the lag ? I am not very familiar with this style of sensor , how do I clean it . I have some sensor cleaner that I bought for my '03 Ford Ranger .

As I mentioned in an earlier post , I am going to do the fuse pull and see if that helps . I have all the components to go back to stock , if the pull doesn't help , I can go back to satisfy my curiosity . The car runs great and I like the CAI . I'm just trying to figure it out .
I do appreciate all the help as this is the first relatively modern GM vehicle I have had so I am on a learning curve .

It might for sure....worth a shot.

It doesnt take long to switch it. If the advice you get doesn't work then maybe give it a try. That way you know. Maybe check the MAF just to make sure you didn't damage it first tho.

^^^ yes this too, those MAF wires are pretty sensitive and can be broken easily if mishandled in any way..

Those stating that the ecu can adapt are correct. But, the maf must be able to read the air flow through the tube correctly. When the intake is changed,, the airflow across the maf can change. Thus the amount of air will be reported will not be correct. Put the transmission in neutral, jab the throttle and see if there is a hesitation. Yours may or may not do it. Different mods, idle rpm and manual or auto trans will affect it.

Does more than just reset the octane to the high table. Resets the fuel trims, basically any volitile memory gets reset.

Ya I know what does ...ive done it a few times but I dont think thats the issue here.

Just wanted it to be clear to others that it does more than "only resets octane table" as you stated. Not sure if the OP is experiencing the same issue as me. Mine is just a brief instance, as if the maf is not responding quick enough. If it is, then obviously it's something else. But it only started after adding the CAI. Same issue with no tune, then a tune when headers were added.

I get what youre saying...but the #1 reason most people pull the fuse is to rest the octane tables. Not very often Ive seen it suggested for other reasons.

So I did the fuse pull and drove my car all week to work (60 mile round trip) and the lag seems to be a little better but not gone . Would a new (different) MAF sensor make any difference ? I saw some aftermarket ones on GEN5DIY website that claim more hp , better response , etc. ?

I would try reinstalling the factory air box and see if its still happening before chasing a problem that may or may not exist.At least that way you know its not cai related.

Gotcha , thanks !!!
