Or the pcm/injector driver.

Didn't someone else on here with a Walkinshaw supercharger have exactly the same issue ?

I think it's the same member in a different thread

OK, there’s your first hard fact.
TVS 2300 on a 6.0, swapped injectors but appears didn’t bother to swap out stock fuel pump.
That is not Holden’s problem, that’s a gross miscalculation to incorrect tune specification by Walkinshaw.
Instead of being a safe and reliable tune, that was bound to happen.
Even naturally aspirated using smaller stock injectors the fuel pump will barely hold 58 psi to peak. Supercharging with the largest (LS9) TVS means more fuel / hp (BSFC), facilitated by larger injector which also means more fuel.
Plenty of info available to demonstrate the stock fuel pump and VF SS fuel pressure control module can not provide adequate fuel and will lean out well before peak.
Pretty major that Walkinshaw don’t up the pump on their supercharger kits, especially the big ones where it swaps in larger injectors.

seriously woundn't they change/upgrade the fuel pump on anything supercharged otherwise there time bombs driving around.

To the OP push like hell to get walkinshaw to pay, there product has failed and even if the pump a bit dicky the super walkinshaw warranty covers that!!!

I'll give Walkinshaw themselves a call tomorrow. Surely this is an isolated issue?

 

[Immortality]

Even if it wasn't I don't think they would tell you.....

Doesn’t matter one bit, the component combo is a timebomb, badly engineered package sold at a ridiculous premium on the express basis that such major defect / damage is covered.

Mod sir, there are two concurrent threads on same topic can we merge please?

 

[Immortality]

Done (just for you Monstar).

 

[lsute12]

I'll talk to them tomorow and see where I get. At least I have the Proof that the fuel and I Hector's are ok
