Stock should be fine.

 

Stock is plenty.

You're very close to the limit of the stock injectors. With just a Vishnu flash and a drop-in airfilter (and 23.5 psi), I was measuring about a 98% duty cycle at 7000 rpm with EvoScan (max value is 108%). With your extra mods, you'll be right up to at least 105% (or more if you rev to 7500 rpm) which is too close IMHO. I think that Buschur has some 660 cc/min injectors that would suit your mods.

 

Stew I hope you get you're car fixed soon.

 

thanks guys for your help!!
