!!!HELP!!! VT L67

Post by Stampy91 »

ive been working on my series 2 VT L67 for the last 8 months. so far i have installed a mace w2a intercooler plate running to a front mount intercooler, 19psi boost pulley, mace ultra high ratio rockers, msd ignition coils, cold air intake, twin 2.5 inch exhaust, extractors, high flow cats. I also had the s/c and lower inlet manifold ported.

I recently just got a NVRAM, figured its probably time fine tune all the work i've done but have no idea where to start.
if anyone coud point me in the right direction, it would be much appreciated

Well I noticed you didn’t mention much about fuel system. The biggest killer on fi is leaning out. How go about tuning is pretty the same on all platforms. Use a base tune, chuck it on the dyno, steady state tune the fuel, find best timing and then finish off on the road

Is it the 25mm or 52mm W2A plate?

Start with lowering timing anywhere above 400mgc to cover yourself while working out fuel control and get a wide band onto her.
