Could i use a dbw ecu and just disable it in the ecu? My truck has actually been flex fuel for a long time and it works with the 3 bar and flex fuel. I just cant turn the boost up, but I'll definitely look into that if I can turn it up that way

 

No, don't use a DBW ecu if you stay DBC. Most of the DBW ECU's don't have the driver chip for the IAC (because they use the throttle for that function). Your IAC won't work with a DBW ECU without the chip.

 

You either need a newer ecm or go with a Holley kit.

 

You could always run Gasoline up to 14PSI, and then pour on the METHANOL to carry you the rest of the way..... You'll need a BUNCH of nozzles, and you damn sure don't want to run out of line pressure on the METHANOL system.

I ended up getting a p59 ecu from an express van, I actually did alot of stuff. I got rid of the turbo that was on it and put a 78/75 billet next gen 1.25 for vs racing on it with a 4 inch fender exit and had frank build me a transmission and put a circle d converter in it. Its currently with my tuner, since we're having to do the tune over since I changed the ecu. I'm on e85 and methanol sounds good but e85 is very easy for me to get and I like to just pull up and fuel up and go.

 

Do got the p59 ecu installed but having trouble getting idle control and tps signal? Any suggestions?

 

Does YOUR P59 have IAC drivers ?

I guess I should clarify: Are you running cable throttle, or DBW ?

 

I ended up putting holley terminator x max on the truck. It made 754 rwhp on 20 psi

 

What FUEL are you pushing 20PSI on?

 

Its flex fuel converted but i only put e85
