Put 200 Jets In i checked out my a/f today with a wideband and with the 150 jets it was 10.4-10.5 i then up it to the 200jets and got 10.7-10.8. mods are in sig, also tune by tsp.
what do you guys think. i took the car from a 10mph roll to 90 and the a/f stayed between those numbers. do you guys think i'll be safe with the 200 jets?
the car pulled great and there was no sign of knock.
thanks

If it were me i'd keep it that way, 10.5 to 10.8 is on the safe side. I ran a 225 dual stage on my last car and plenty of people run alot more.
If you want to be absolutely safe take it to a dyno and make a few pulls to verify a/f. It's pretty cheap and a good way to see how accurate your a/f ratio gauge is.
I hope you're running around 2 heat ranges colder than stock with a slightly smaller plug gap than on the 150...

If you have a custom tune advanceing timming I would pull about 6-8 degrees total for the 200 shot. TR6 plugs should be fine. I would shoot for a airfuel of 11.5-11.8.
Make sure you have enough fuel pump.. And if you have a stock bottom end just know you are walking on ice.
