I heard now it can be done with the 99 and up stock computer. I don't mind getting the parts but need help with install and tune. Car has a Formato tune that has been corrected in regards to driveability issues....

Glad you corrected that Formato tune. Can't tell you how many **** shows i've fixed that have come out of his shop in the CTS-V community. His tuning has got sloppy as well. As for flexfuel on a LS1 0411 PCM, here is a thread dedicated to gen III and flex fuel. https://ls1tech.com/forums/pcm-diagn...-write-up.html
Beyond that, install of the hardparts is actually pretty simple.

Don't blame you one bit. I started to have him tune my V when I first moved to Florida last year, but after speaking with him at Cadillac Attack, eavesdropping on a conversation he was having making ridiculous claims as to why two cars he tuned were running like ****, and seeing another tuner take the car around the parking lot to tune it shave half a second off on the first pass, I ended up having Justin White tune my V. If you need any help with the FF stuff lmk. I've installed a few kits though never on an Fbody running the 0411. I'm just up the road in Cocoa/PSJ

Car ran good at WOT but driveability sucked. Stalling out etc. I know a 102TB/MAF is a pita but bucking etc was embarrassing especially when others back in MD had set up with T rex and drove nice. Spider worked on it and its way better though he is not 100 percent happy.
Yes I do need help I have very limited time for car. Car is in the middle of doing a vacuum pump on it. PITA with tilted radiator from ram air and still has AC. I am in Rockledge and we have a boat at Harbortown so that is no problem in regards to location.. Problem is having multiple hotrods. Drugs would be cheaper hobby and less timing consuming

TBH you're not going to notice a difference between E85 and 93 unless you're boosted or high compression. My 13 GS was full bolt on, heads, cam, etc that I put flex fuel on and it only saw a 14hp difference throughout the curve on E85. Was like 577 on 93 and 589 peak on E85. It smells nice though lol, but its something to take into consideration before you do it. Theres a good possibility you're going to need larger injectors as you will more than like max out though 42s. You'll also need the flex fuel sensor, a harness, some fittings to add the sensor inline with the stock rail, and access to HPT to flash the new OS

I had the exact opposite experience with my CTS-V. I had a bad experience with Justin, and Jeremy was able to fix the car and got it running very well. Justin also had a crazy amount of timing in the tune and had me doing WOT pulls... I was lucky it didn't hurt the car.
