I've looked into Hahn Racecraft's Portfueler, but I want something where I can tune my ignition and fuel all in one, instead of having two or three different things to try and tune. Can you please help me with this big problem?Bobby Harris

Bobby, you are on the right track. Using one system to control everything is going to work better than using three different system trying to do three separate tuning duties. A stand-alone will be best but you will have to figure out how to make your factory gauge cluster work if you are still using it.
Your other choice is to use a piggy back computer that has more parameters than the S-AFC like a GReddy e-Manage or e-Manage Extreme. Both e-Manage systems will allow the tuner several different tuning points to control injector duty as well as control ignition timing.
Dear Turbo,
I've just got a 1999 Nissan Maxima from my parents as a high school graduation gift. Now I am going to start college and it is expensive! I want to start upgrading the performance parts but with college I am on a budget. I realized that the Maxima's engine has real potential to be faster and more powerful.
The first upgrade that I would like to do is the air induction. Due to my budget, I can only afford a short-ram and not a cold-air intake. My question is: Should I keep the stock intake and just get a performance drop-in filter? Or should it be a short-ram intake?
The problem is that the factory unit sucks in fresh air coming through the grille and I like that, but it is pretty restricted due to all the silencers. With the short-ram, my friends tells me that I won't get any power because it sucks in hot air from the exhaust manifold and radiator fans. So now I am stumped.
Is the fresh air from the stock intake going to make up for the restriction? Or is the direct flow of hot air going to interfere with performance? Any feedback for my breathing problems from you would be great. Thank you.

Quan, as you may already know, a cold-air intake would work best on your Maxima. Between choosing a short-ram intake or a stock upgraded panel filter we would go with the short-ram.
Although the short-ram system will consume some hot air from the engine compartment, the increased temperatures should not hamper the performance gains from the system.
Secondly there are some companies that sell upgrades for people who purchase the short-ram and want to make it a cold-air. This way when you have some extra cash you can upgrade the system to a cold-air down the line.
