It won't boost your 55# injectors to 72#.
The seller implies on his webpage that this spring boosts most injectors to a flow rate of about #72. The real truth is that you already need to have 65# injectors to reach 72# like he claims. The truth is that most people have #55lb injectors, not the #65 required to boost them to the #72 he implies. This will only boost a set of #55 injectors to 65#, far short of enough to support the 270 horsepower implied on his webpage. He implies this spring avoids the purchase of higher flow injectors. That's false for the large majority of us.
