Need Help - Super Charged Methanol injected studders Bad at half throttle. NO Codes
Super Charged Methanol injected studders Bad at half throttle. NO Codes on the car. I bought HP tuner and ran VCM scanner and recorded a pull of when it does it. The car studders badly almost like it hit a rev limiter anytime I push the gas pass 1/2 throttle. However if I roll into and dont go past half throttle I can take the car to 5K with no hesitation. Its seems to happen right when the methanol kit light comes on. So I would like to resolve this myself but not sure where to start.
History - had some stumble (not like above)
Changed wires and stumble went away. (3 months ago)
had fuel rail replaced and they rewired the methanol to be outside fuse box under hood. It was overloading/burning up the block the original owner put it on, they had added it to the fuel pump fuse block. When I got car back a week later it started this mess so not sure if its a coil or
Car makes about 730 RWHP but driving it around its fine and drives fine just anything past half throttle it studders and stumbles and loses all power.
