The 25* injector is rated as 3.91 G/S as the 8* injector is but the 25* injector has 6 spray holes vs the 8* 3 hole nozzle which makes the 25* injector flow 15% more fuel plusit atomizes the fuel better.

I had problems with the stock 8*, dealer replaced with 25* under some hidden semi-recall.
Lots of surging and stalling issues for me.

IF the bike ran good with the 8degree injectors, replace with them.

PCIIIs at least, have almost no maps for 25 degree injectors on 06 TC88s. The are definitely richer.

I also had the cold start & surging/hesitation issues with the 8's. The 25's are way better in performance.
