Hi all,
I'm the proud new owner of this 93 Skyline GTS25t, I used to have a 4-door version a few years ago, I couldn't stay away
Anyway, its relatively stock, having just a cat-back exhaust, hi-flow muffler and cheap looking bleed valve boost controller. I'm planning on fitting a better dump/front pipe, and the car came with a Blitz dual SBC that I'm going to get installed. The next planned mod was getting a tune, and that's where I'm not sure.
One of my workmates is offering to sell me a Greddy piggyback computer for $100, but I was also considering getting a Nistune. Being that Nistune's cost around $400 to buy, the piggyback is obviously much cheaper. As of now, I'm not planning to upgrade the turbo(hopefully no AFM issues), so I was wondering if it's worth spending the extra dosh on the fully customisable ECU?
To explain further, this Greddy piggyback resulted in my workmates R33 putting out 260rwhp, with pretty much the same mods I listed above. Another friends R34 is putting out much the same horsepower, same mods with a PowerFC. I know that the peak power only tells half the tale, can anyone comment whether low down/off boost/midrange is much different with full tune rather than just air/fuel?
