i have an 06 enthusiast auto w/ 2,700 miles and planning to put plenum spacer, gains will be between 6-16 whp, now to get the gains will i need to have a reflash or will i get it without getting it. So far JWT pop charger is the only engine mod i have now.

 

If you have the revup engine I think you don't see much gains with a plenum spacer and should consider the MREV from Motordyne. Search around and there's lots of info about it. What ever you get though a reflash will not be needed.

 

The plenum spacer would still help - but like stated above it might not make the same HP/TQ gains on earlier models...AAM aslo has an angled plenum spacer and could do your relfash if you wanted. (The general rule is to wait for a reflash until you've done all of your power mods, other-wise you'll be spending extra $$ to reflash after every mod.)

You have the revup motor. See the intake forum for recommendations.

 

Actually the 5AT does NOT have the rev-up motor. The gains will be the same as the other 287hp engines.

 

Oh and to answer your question: reflash after your done with all your breathing mods, otherwise you could end up wasting lots of money

 

If you have an A/T, all you need is the Motordyne 5/16" spacer. I highly recommend you order it with the ISO thermal kit.
