[QUOTE="PNWSVT, post: 16179165, member: 192698"] * My current tuner is awesome and am not saying anything against his name, he's doing a great job, im just asking for some outside help. Maybe someone else has had this same issue? I am so angry that I have typed this about 500 times. I am not angry at anyone in-particular just with this car and the overall process. I wont say what isn't wrong with the car because I don't even know what is wrong with it, and neither does anyone else. What I can say is this: [LIST] [*]My engine has been rebuilt within the last 1000 miles. [*]As far as I know and tuner number 2 knows, my car has no mechanical issues. [*]Tuner number 1 wanted me to replace my Comp Cams with factory cams because he thought but wasn't sure, that I degreed my cams wrong. [*]He thought this because his tune has about 20* of timing around the high idle he gave me of 1200 rpm [*]Tuner number 2 provided me with a base tune and a few adjustments that had timing at 0.00 at idle and it purrred like a ****ing COBRA KITTEN. [*]This made me and everyone else think that if it truly was a cam timing issue, by this point, it would have bent a valve and broken my soul beyond repair [/LIST] I have replaced the following parts during this whole tuning process: [LIST] [*]Upstream o2's [*]TR6 plugs @ .028 [*]Oil & Filter [*]FRPS [*]Oil Catch Can [/LIST] Latest tune process as follows: [U]My initial WOT 3rd gear pull (30mph to redline) [/U] AFRS 12-12.5 range one upstream sensor was disabled (for exhaust balance issues) [U]2nd WOT 3rd gear pull (30mph to redline) [/U] Major hesitation at low rpm (did not exist in prior tune) AFR's went to 10.0 STFT bank 1 and 2 went opposite of eachother until WOT run at which point they went to 1.03 and 1.05. At idle after my WOT run Bank1STFT 1.3 Bank2STFT .88 Now i asked if he had turned on both o2 sensors in the revised tune and he said the following "No, the only change between that and the last was just WOT fueling, something else had to be going on. I took out 4% out at 550MAF counts on up, should lean it out to perfection. The log at 200 maf counts, the o2 sensor removed 28% fuel and still didnt switch. It was perfect before at 200 maf counts, no reason why it shouldnt be now." he sent a revised tune and it acted even worst with my STFT on bank 1 going to 1.99 and then bank 2s in the 1.08 area. When I get on it they both go to around 1.03 but then afterwords they do what they want and bank 1 skyrockets again. I replaced the FRPS and now the STFT are a little closer, but it still bogs out and takes fuel out for whatever reason. CAN ANYONE help figure out WHY it would remove fuel? Why a tune would work one day, the next it runs like shit? I have a VMP GEN1 blower that used to be at 19psi now at wot its only around 15psi. so not sure what thats all about. SCT BA3000 Fore everything, return style, dual gt pumps (running full time) 63# injectors EGR delete DSS GSX forged pistons 8.23:1 Comp STAGE 3 cams (beehive springs etc) ARP studs, bolts you name it Canton pan with windage tray etc etc etc [/QUOTE]
