I have a 99 automatic maxima and I have been debating on what mods to get for my car. I plan to go with frankencar intake for sure. 18'' rims are also coming soon so i think it might slow my car down even more. Right now i'm trying to find the mods to improve mpg and speed. I usually have the overdrive on to save fuel so maybe thats why i'm losing some power. Recommend anything (ie: ECU upgrage,UDR pulley,y-pipe,etc) Thanks

 

search is your friend.

welcome

 

All your answers can be found here or here

 

UDP= not really worth it...minimal gains for big$$$
Y-pipe= definitely worth it...good HP gains
Don's VB= a must for all automatics.....quicker shifts
ECU Upgrade= you're looking at a 3 week delay. JWT is backed up.

 

the word AUTO and SPEED dont belong in the same topic line

J/K a well modded auto can kick some *** though

 

If you've got a '99 (or 97+ for that matter), forget about the ECU Upgrade

 

Have they just not come out with it yet?? or is it impossible for them to make it?

 

So far its been impossible. But we've been keeping our hopes up for one to come out. (I plan on buying a 98 as a second car.)

Get an intake and a y-pipe. As for the UDP, I'd hold out on that unless its the only thing else you can do before going forced induction. It doesn't give enough power for its cost.
