[QUOTE="TheBab, post: 139179, member: 9173"] First off let's start off with car and mods.. 1998 Cobra with the following on it... - Engine - Engine was bored 0.030 over, Manley H-beams, DSS blower pistons with 8.5-1 compression. - Vortech S-Trim Supercharger w/ 3.33 pulley - 24" x 12 " x 3 Polished front mount intercooler - 42lbs. injectors with a lightning 90mm Mass air meter - Walboro 255 fuel pump with T-rex pump - Flowmaster mufflers - Bassani X-pipe - FRPP shroty ceramic coated headers I have a few questions .... [B]Boost Question[/B] It was seeing 10 psi before the intercooler install....I installed the intercooler during the winter so I couldn't go test it out... but all my clamps are tightened down damn good so I'm 99% sure theres no leaks..... all I am seeing is 5 psi at 6,000 rpms... I knew I was going to lose some boost but 5 lbs of boost? Any ideas on what this could be besides intercooler? Anything I should check? [B]Idle Question[/B] When I turn the car on.. it idles high for a second.. but then drops back down to about 1000 rpms... it wont go below that... Shouldn't it be lower? Is there a way to set it? Then when I am driving around.... and I come to a stop... put the car in neutral... or even in gear... at a complete stop and clutch all the way in... the car will idle at like almost 2K rpms... for like 10 seconds or so... then drop back to normal idle (well my normal idle of 1k) .... what could cause this? [B]RPMs question[/B] I bought the car with the vortech and tuning done already.... I got the charts.. but the dyno was shut down at 6k rpms when it redlines at roughly 6800 or so... If I try to take it above 6k it falls on its face... I'm not sure why this is... my only thought was I am pegging the maf? Any clues? Yes, I know A LOT of questions... but I just want to make sure I can get this car running great... I appreciate any help or answers. Thanks, [/QUOTE]
