What to expect - 19lb Injectors - MarkD Chip for 19lb

What can I expect for this?

t3h fastness. Thats what.

hmmmm

Don;t get 19lb injectors

Go with 17.5lb instead. 19lb injectors are too much even with the chip and M30 AFM.

Get the 19 pounders and MarkD's chip for the 19 pounders and youll be fine.

I still cannot see the m30 afm doing anything as an upgrade... Possible but unlikely to me.

MAF on N/A and MAP on F/I

On another note, where the fuck do you get this chip? I tried emailing both address and pm'ing MarkD on both boards, no response. Makes me not want to send him my $200+ dollars and just HOPE I get a chip in return.

Unless you plan on going turbo or boring and stroking the engine, replacing the AFM with a MAF conversion and tuning them in with an AFPR then 19lb injectors make you run too rich above 4K.

19lb injectors are really too much for a stock M20 w/ just a MAF and a MarkD chip. Trust me I know.

If you ever get a chance to compare your stock AFM to a M30 AFM you will see that the M30 AFM is much bigger = more air flow.

Just being simply bigger does not really mean anything :) Bigger means more airflow up top but a possible loss of torque down low. For the time it needs with taking it apart and swapping this to here and there I would rather Tune my own MS

19 would not seem to big to me. Consider the OEM injectors are running at close to 100% duty cycle it would seem that 19lb injectors would be a good fit.

tell me about it. i ordered a chip in december and got it in late february. you have to go on his site and call him directly to get any answer. emailing is useless. your other best bet would be to buy one from irelandengineering if he still has some. i know the Mark send some chips out to the westcoast and eastcoast and has them as dealers because he's in Canada.

I have never had any problems contacting Mark D, email or pm

I am waiting for a reply now :)
