I just bought my injectors for my TVS 2300 cause I bought the tuner kit.
In the end I went with the id850 injectors cause of 3 reasons,
There suppose to be the best because of the flow data where others don't have that. Second was cause my tuner recommended them but also said he had no problem using the FAST ones as well.
And third and finally the most important reason I went with them is because I got an unbelievable deal from a vendor and you can't get them for the price I paid...
Actually I think the vendor got in trouble and was forced to take down the ad
