Got the turbo mocked up. The manifold runners arenít the best design so intercooler piping will be a tight fit.

You don't have to go standalone.... i'm running 17- 18 psi on Ali's TT ecu mod. Where you just use a Supra computer(300) a MAP and an intake air temp sensor, move like 4 wires and add coil pack(big win!) for 500-600 you can have everything you need. Plus if u want to go standalone later just get the AEM sensors(intake air temp, air/boost pressure sensor now use them with tt ecu until you upgrade and its less then

I tried what your doing first with only 550 cc injectors and ALMOST a standalone, I used the AEM FIC-8 to control everything. I kept the MAF because i was thinking like you that i could make it work. I made it work okay at WOT but normal driving suffered espeically in situations where your going in boost then need to stop all of a sudden, the blow off valve dumps your air because you just closed the throttle plate and the MAF has no idea what happened to all that air and the car dies. Since your stopping theres no new air coming in over the maf or not nearly enough.

I'm running 13.5 second passes at 6000 ft on 440 cc injectors and the tt ecu mod with a cheap xs power turbo kit, i've replaced alot of it but the turbo and intercooler are there still.

Do you really think everyone is wrong telling you the stock computer wont be happy and you wont be happy? or are we all trying to help you save time and money? because we all already tried it lol

I still plan on going full AEM standalone but thats after i upgrade my transmission/turbo and am ready to push past my 350-400hp and push for 600 or 700 i've had the car running the xspower turbo and tt ecu for over 2 years and 15,000 miles already.

I also ended up taking my turbo blanket off because it hits the stock intake and actually transfers the heat to the intake pipe physically. Yours may not be the same but be aware

To get more scientific, running a methanol/gasonline mixture while also adding a cosolvent (ethanol), will give you an even leaner mixture. Running straight methanol is difficult as it requires twice the fuel system parameters as gasoline and is also extremely corrosive. However, adding a cosolvent prevents it from separating in the mixture. While both alcohols, ethanol is distilled from organic matter while methanol is a product of carbon monoxide (itís extremely poisonous).
You my friend have no idea what you are getting yourself into!! Do not waste your time on piggyback. 98% of the guys here have tried it 15 years ago and it just doesnt work plain and simple.

Running e85 or E98 will not lean it out the right way..you will end up melting pistons.

Made 700whp on stock Ge headgasket , stock head bolts, un-opened GE motor with 170k miles...

One Advice though, if you cant afford to do it the first time, you definitely cant afford to do it wrong...because it will cost you more to fix it the second time around.

Good Luck with whatever direction you decide to go.

Definitely skip piggyback if that was a serious statement.

What's up Omar , good to hear from ya .. dunno why those who are upcoming in this game of boost especially under na-t don't see the writing on the wall . I hope this thread starter will reconsider and do this the right way and go standalone and have a setup that will run correctly. I can say with authority I've taken down cars making 150 more hp then me in friendly runs over the years . Can't do that on stock GE ECU
