i'm about to buy either those 530, or 630. Are the 630 worth the extra 100€ for them?

0280158117 (530cc, 6-hole spray, 15deg) ~200€/set
0280158298 (630cc, 16-hole spray, 20deg) ~300€/set


because they are short nozzle injectors I might lean towards the cheaper one with a slightly smaller angle, to prevent wall wetting as much as possible. Anyone have thoughts?

Hi, I have 0280158117 550cc with 4bar or about 630cc and after deceleration under low load I still have a little jerk and I am still asking myself the question of TEMIN without really finding any values ​​or calculations.
 At idle te 1.5ms.
 temin 0.299 is it too low? Thanks

I went back to the original temin ~0.85, it's hard to say if that's better. I read somewhere here that a good base would be te less the smallest tvub. Or my problem is elsewhere, maybe my closing cards because they were taken from the s3 in file 150...

Can someone tell me which map to change when the car doesnt start on its own?
I always have to touch the accell pedal slightly to give it the last 10% so it will start.
