Location: An island off southern Tasmania.		If you have upgraded the size of the 7th injector for the Sprintex supercharger then you may find the following re-mapping of the timing and injector settings useful.

The attached screen shots are of my dyno'ed GT after the injector was upgraded....the screens are for petrol only mode.

The last map screen is for the special case of an LPG supercharged tune as per my GT....when running LPG/Petrol mode.

Standard 76mm pulley...but with bigger injector.


but look carefully...no 7th injector pulse until around 4000 rpm...this is cause I have lpg as well.

Yours will be different, you can cut the 7th injector in way lower, based on 50% throttle position.

You can play with it or get it dynoed....I got mine dynoed then tweaked it.

Since you have no LPG, the cells below 4000 would probably have something in them, drive around with the laptop and an assistant, if it bogs down at a certaqin throttle position and rpm then thats where you need to play.


Compare it to the stock settings as well.

Just reading up the part number of the Bosch injector that's included with the blower kit. Turns out it's a commonly used injector in ford falcons. 190cc injector. I'm dropping it in favor or 6 larger 470cc ones up from the stock ones.

yep...a better idea...as long as you can retune the ECU...in a 380 its not an option, the SMT6 essentially just drives the 7th injector.

Location: An island off southern Tasmania.		I can send you my spare smt6 with the tune already done if you want?


then just plug in and see what you think....even stuff up the settings if you want a play...just send back to me when done?
