Turbo 350 Injector question...

OK... A bit noobish but I'm kinda up against a wall.

My cars has had a intermittent 'no-start' issue for some time. Over the last few days its gotten worse.

After MUCH trouble-shooting and many parts, I read on this very forum that a couple of dodgy injectors could cause this to happen. So I tested them and got these results;

1 - 16.8
2 - 16.8
3 - 14.4
4 - 11.7
5 - 16.7
6 - 6.7
7 - 16.7
8 - 16.9

So obviously I have a problem.

My question for this thread is; What replacement injectors would you guys recommend for a 350 TPI, running 6.3PSI of boost with a big *** intercooler?

Annnnd... Since i'm in a MEGA rush (this all has to be done by next friday for a finals meet), would the car run with the bigger injectors WITHOUT a new prom tune? All i'd be able to play with is the rising rate FPR.

Or would you recommend my buying 3 injectors to get me buy until I can sort out hte bigger ones properly. Bearing in mind my location and the need to use fairly generic/accessible brands.

Re: Turbo 350 Injector question...

Basically yeah. Its was a prom tuned for a set of 24#s back before the turbo. Just been using a rising rate reg to up the pressure with boost since then.

Found myself a set of Saab 24#s locally for cheap, so they can keep me out of trouble this week until I can get some 32#s and a new tune.

I've got some 30 lb SVO's sitting around that I outgrew... You will need a re-tune, though. Send a PM/offer if you want them.
