In warm temps....
 

my 2004 h2 w/ 30k on it seems a bit sluggish after approx. 10 mins. of ridin around..?? When leavin it seems normal, but seems to lose power if A/C is on or is around 90 out....Is it normal or could something like ig. switch be doin it...?? also battery light stays on for 5 sec. after shut off which ive read does relate to switch.....my only mods are Magnaflow exhaust and throttle body spacer...I was thinkin maybe to large exhaust when air is so minimal at 90-100 causes a little decrease in performance....
