sefi fuel pressure regulator problems?

my quess is they only added timing to your chip. which is basically a high octane program that basically advances your timing from 10 to 14 initial.

slight idle surge? your tuner can fix the hot start problem very easily as im almost 100% its a meter issue. too much fuel at start requiring you to open throttle to lean out by adding air. sometimes you can open the throttle just a bit to fix or drill a hole in your butterfly.

It loops and surges sometimes in idle. Thanks for the info!

It shouldn't do that. Should hold pressure within 5 psi of max for at least a minute.

Thanks for all the info Dave! I'll keep you posted!
