We had Lee's Integra on the Dyno on last Friday. He came in with a Phearable.net Base tune. This GSR had a B20 VTEC with some regular bolt-ons. .

Here is the setup:
B20 VTEC
GSR Head
Stock GSR Cams
Stock Intake Manifold with IABs deleted
eBay Header
Short Ram Intake
Megan Racing Exhaust
Adjustable FPR

Tuned on Crome Gold





The Red graph is a Phearable.net base tune, and the Green graph is our tune. The base tune was so rich that our wideband could not read it, and the VTEC crossover point was way off.



Also, I would like to add that running as rich as this setup was, can wash out the piston rings over time and increase blow by which also hurts power. I would imagine that after 1k miles on the new tune, power should increase since the rings should be "sealing" back up.

Damn, forget the peak differences but your tune beasts that base map in so many ways I don't even want to start.

Great job guys, looks like a serious improvement over the previous tune.

Thank you sir.

I could use a tune... :'( My motor is capable of far more power than it's making (from my last dyno session), but that only went up to 5300rpms for some reason. I need to figure out what kind of tuning programs/systems would work for my car.

its a nissan. nothing works for them.

nice tune guys. i need a tune on the mustang... i'd bet i'm running pretty lean on the top end. do you tune with a tailpipe sniffer O2? how's that work with 2 pre-cats and 4 cats?

We use a standard 02 sensor. There are different ways of getting an accurate 02 reading depending on application although the vast majority will work by placing the wideband at the tailpipe. On cat vehicles, ideally you want to place them before the cat although truth be known there is often little to no difference in readings as long as you are 2ft away from the the head or turbo. Turbo cars tend to be picky about this.
