I am getting ready to put on the GYTR slip in exhaust and I have researched on here and it looks like most go with the PC III....but that is for the full exhaust with the air box lid removed (or at least that is what I have found so far). My question is do I need to get the PC III if I leave my air box lid on. I realize that should somewhat defeat the purpose of the new exhaust, but I'm hoping it is something I can do at least until I buy the PC III. The guy at the shop told me when I got the exhaust that I dont need to map it, but it's looking like most of you disagree (again thats with the full exhaust set up).

thx

Mike

i did the same thing you did, only with full exhaust. the dealers said i would be fine they could tune the fuel curve to allow for the exhaust. i got it home and it ran like total shit and popped and back fired, ordered the PCIII and intake and now she scoots just fine. so i would say if there is any way u can get a PCIII you need to get one, but you can always try it and see.

Im no pro but I've been running a gytr slip on with lid on for 6 months now with no programmer and have had no probs yet. according to my plug It's not as lean as it was stock. before it was white. now it's light brown. I did however order the gytr headers, adapter and filter and a pc III today. I'm all excited. with luck I'll get it all by friday, but we all know how that goes. it'll be monday. :crazy: I chewed the stealer enough till he gave me 10% off of the pcIII but I spent 700 and some change. I can't wait.

yes u need it. there have been several proven cases that you do.

99% of people on here will agree im pretty sure. plus why risk an engine to blow up for a 280 PCIII?

just be 100% safe and get the PCIII

check your plug stock then put the slip on on and check it again if it's browner(as long as it isn't too dark) it's not going to hurt anything.if it's to rich all you'll do is foul plugs. if you do anything to the airbox you WILL need a programmer. doing a plug test with a slip on on won't blow your engine. if it's the same color or whiter i wouldn't risk it. if it's darker you are good to go. but i would buy a pcIII if you can afford it anyways because there's no sence in opening the exhaust if you don't add more air.

I have the slip on and the lid on. I did remove the air box and it did back fire without it. So it must make a difference. Leave the lid on and ride like that until you get the PCIII. It sounds much meaner with the slip on!
