I dont really have any more bolt on mods to do aside from headers and an underdrive pulley. Headers are extemely expensive and require lots of work and do my research in the stickies doesnt have significant gains. I found a set for 200 bucks on a website...but before doing that wanted to know if anyone had a noticable difference in their max after the install. Thanx for the help

 

a set of what? a UDP is a single item. and no there are not significant gains from the UDP or headers on our 4th gens. the reason why headers are so significant on 5th gens is cuz they have precats in their headers, where all of our precats are on our y-pipe.

but if you really have done everything else, I/Y/E 00VI, ecu upgrade(or piggyback system) than yeah those are basically the next things you can do for the extra little HP

only reason i have a UDP is cuz i got it for dirt cheap w/ belts. i would def do 00vi or a piggyback system before headers. my next item is a emanage ultimate.

 

+1 tuning might do you some good, even with just bolt ons a/f's can be adjusted throughout the curve to make better power. For the money the Greddy Emanage Ultimate is a heluva thing to get to tune

check www.forgedinternals.com for a really good price

 

is the EU all worked out for us maximas yet?

 

EU??? 12345

 

Emanage Ultimate?

 

I think they are waiting on a crank position sensor input so we can adjust the rev limiter and timing, but the a/f works, correct me if I'm wrong.

 

ask DandyMax about that....
