Best tune for m20b28

(1/1)

ifty:
Hi iv got  a 1990 E30 cab which I have done a 2.8 stroker to it. iv got the 3" maf with the war chip.

to do the 2.8 stroker iv used the m30b35 injectors, 290/290 cam big bore throttle body and a full stainless steal exhaust from the manifold (headers)

What is the best tune for it, iv used the tune the is in the tune room but it is no good.
Iv used 173 ecu.

All help is appreciated as I don't no what to do

Hi,

Use the stroker base tune. Make sure you installed the MAF correctly by going through our trouble shooting guide listed in the manuals section of our website. The stroker base tune is meant for the 3" MAF, 19# injectors, stock fuel pressure and the usual bits and mods that come with doing a stroker.

Please email us the air fuel ratio using the stroker base tune and we can modify it from there. It should be pretty darn close and if it is not, there are other mechanical problems affecting your engines tune.
