DO you have to change the MAS to run a 4# lower on a 99L? I want to order an intake kit and am worried I'll have to get something else down the road. Any suggestions would be appreciated,Thanks.

 

Not for just a 4# lower. Yes you will have to change it out as the mods start comming in.

 

Do you mean changing from the factory 80mm MAF?

I've upgraded mine to the 01-up 90mm MAF and run a 4lb lower pulley and my MAF gets up to about 95% in warm weather. So if you are running a 4lbs pulley on the 80mm it's definately possible that you could peg it in the right air, but probably not enough to throw your tune off.

 

Thanks,I have a single blade on it and want to put 4# on later. Was wondering if MAS needed changed.Is the K&N setup any good or is there something better at about same price?

 

oh yea forgot to mention;The truck went out this morning for install of new monster box.Haven't driven it in a couple months.Can not wait to get a few miles on it. I hope I,m not getting more problems. besides my girl wanting to shoot me for spending the cash.
