Add more fuel. How are you reading your lean condition?

Riva ecu and 50lb injectors. This is the best way.
Or rrfpr. Requires tuning.

Just cause the tip is melted doesnt always mean its lean..If your using that to judge if your lean or not puts you way out in left field..Last year i ran a first generation RR SC wheel,4 inch air intake,42's and external IC...I also melted my tip..My A/F readings??I was running a tad rich through the whole RPM range..So if i was running rich why did the tip melt?? The ONLY way your gonna know your running lean/rich is to put an A/F guage on..

I have to agree there. LM2 for sure.
One thing I have noticed is if theres a chance any air gets drawn in at the manifold union at ALL, then it will get very hot just there, ...which I think has been covered in this forum somewhere, but always try to get that mating surface clean, and as snug as possible.
