Hello
First time with nico
Questions is : it pulls fine through first gear no problem/ builds boost but in second it won't rev past 6k, its like hitting a fuel/spark cut. my rev limit is currently set to 8k.
I went through my couplings but didnt find any leaks

problem is the ecu, its not tuned for a z32 maf or 550s...god only knows what its actually tuned for.

[Black_label_240sx]

id agree. so i have around 1k budget for a new tune/ecu setup
whatvsetups would you reccomend? ive heard of nistunes and aem setups but never played with eitgher of them

AEM cost more than 1k. Nistune is around $550 with the software if you want to tune yourself. If not get a rom tune from Carl or who ever.

Alright, so what do you think of nistune ? How easy is to tune for first time-ers. Good support from nistune ? Does it allow for more agressive builds later down the road? I understand that it really isn't a standalone per say but just changes the parameters of the stock ecu.
Whats the pros vs an AEM ems ? ( besides price )

IT's some what easy as long as you don't try to break new ground. Stick with the Z32 maf because the current VQmaps they have for the Lightning maf don't work so good. He gives you support on the hardware but not so much with your tune lol. The forum is helpful so you can prob find your answers there. I run Nistune with 800cc sard injectors and the lightning maf.

if you are interested, i can set you up with a proper rom tune to suit your setup...email me.

I appreciate it carl, but I decided to go with an aem ems setup since I want to learn how to tune my own car, and i have a buddy ina shop w/ a dyno that can help. Also for future builds it seems like a good platform to use.
Nistune will be a buy sometime in the future for experimental reasons.
