I did e-mail the person from UPsolute back, and told them that there had been a guy from UPsolute on the forum trying to get members to get together and do a group buy. I also told him that the members wanted proof of the HP gains, like a dyno sheet but he did not provide anything so nobody that I knew of was willing to do the upgrade without proof. I did read somewhere in the forum that someone did get a upgrade from UPsolute for a regular xfire coupe and they posted that they could tell a difference. I did also try to e-mail a Jesse person at Evosport I believe, but got back a undeliverable message, I had read somewhere in the forum about him doing ECU upgrades, and that he was a good person to deal with. I did get a phone # from the thread that I was reading about him, but have yet to try to call him.
