I apologize for being disrespectful Ted. You do give excellent and the correct advice and the forum is lucky to have your help and support.
We are all free to our opinions correct? As long as we are not being races, hateful and disrespectful. My opinion Personally I don't think you have ever tuned a car that's running both( port and DI). I've purchased many parts from you in the past 10 years with my 5th gen. And I follow social media heavily. So, I've been following the great things JMS has done. I have not seen one procharger build that supported DI and Port that left JMS remember the XDI option only been out for a year or so. Are you telling me no one from the end of 2013(c7) to 2020 wanted a 1000 rwhp vette or camaro on pump e85.. Port and Di or race gas would of been the only way to make that power correct? I guess you could on meth. How did you build untra dependable 1100 rwhp cars before the xdi that drive across the country?
I'm not trying to put any shop down merely here to inform/ help people and let them know there are other ways to fuel these cars properlyif you don't have 14k. I've been running about a year now and other than dirty injectors I haven't had any problems w port. And it looks like my buddy Peitz Performance is doing some good things with DI and Port to Emily's c8.
On the price of $14,000 I'm including the xdi, fore, and labor here is a quote from JMS.
There must be a need for it otherwise Toohighpsi wouldn't of came out with rails that mount between the maggi and heads.
Yes I agree DI is more efficient and will always make more power. But DI is limited on injector size as of now. I'm at 1044 now not because I'm out of injector or because I can't make as much as DI. I stopped because I have a stock block. I have enough fuel to go to 1400 hp if I wanted and I'm still at 8.3 lower and 3.0 upper. I can get a dsx 10.0 or 9.84 lower and a 2.75 upper and make some serious power. So the argument that DI is more efficient and makes more power can't really apply here yet. I have no idea of gas milage but I do know I can make more than the xdi as of now. My car drives like it has one type of fuel system just like the c7 zr1.
