getting my mailed in frost tuning

[zeetwentyeight]

i have a 98 z28 m6 im sending in my pcm to frost and noticed is said they delete the AIR and EGR what exactly am i gaining from that? And will i still pass a obdII test? oh and if it helps have 3inch catback and free ram air mod and painted calipers haha thanks guys

it just means that if you plan on doing long tubes and delete the air and egr system that it wont throw a code. it should still pass emissions but i am not sure, it wont have the dtc stored so it should be good. also Frosts tuning will really wake those painted calipers up

Good point and I was wondering the same thing

Painted Calipers= Horsepower

Dont forget Greddy stickers down the side panel and huge aluminum spoiler do long tube headers eliminate the o2 sensors? is there an advantage to long tubes?
Cause headers and y pipe is is in the next couple steps for me.

Deleting the AIR and EGR is just removing the SES codes it would pull. If its still on the car and functioning, I can't see why you would not pass an OBDII test.

Long tubes eliminate the rear 02 sensors, you will still have the front 02 sensors though. Without the rear 02 sensors in place, you will pull a check engine code until you have the codes deleted. It will not affect performance adversely though.

The biggest advantage to long tubes is when you add a cam and other mods. By adding mid length or long tube headers, people generally see 15-20 RWHP gains. Now if you added a cam with mid length headers, you might pick up 25 HP with the cam where as you would have gained 35-40 HP with a cam and long tubes. Long tubes allow you to expand more than mid lengths do.

Alright but the frost tuning deletes those rear o2 codes and i will be alright with emissions?
Another thing i wanna do is get a ORY but would still like so swap with my stock y-pipe with long tubes on for emissions is this possible or would i need to swap headers as well?
Thanks for the good info helps alot

If he deletes the rear two O2 codes you will pass OBDII emissions. Deleting the O2s (I think) sets them both to a preset value (constant) so that the computer is fooled into thinking they are still there, and working properly. Thus this is why you won't get a SES light.

Your stock y-pipe won't work with long tubes. You will have to get an ORY or a catted ypipe to work with long tubes.

35th answered the part about the rear 02 codes above me.

Damn alright was hopin to be able to pull that off cause i know they will pull a visual inspection on my car utah is a pain in the rear

do not keep the stock y-pipe. if you've ever been under the car im sure uv noticed the oval(flat) pipe on the driver's side of the y-pipe. that hurts flow so badly.
stock y-pipe=slow

well i just wanna be able to swap them out once a year for emissions
