91 Tune Problems
Im running Brenspeeds 91 octane performance n torque tune, and before i email Brent i wanted to see if anyone had the same problem,
When im taking off(any gear) below 3000 rpm the throttle lag is worse then stock then once i get above 3 grand boom it takes off like a bat out of hell, iv already tuned it back to stock then re loaded the tune same problem.
When below 3000 rpm it really feels worse then stock the lag is crazy.
During lunch today at work i was racing my buddyon an abandon straight away road and i was power shifting i won not thatit matters right now but i then relizedwhile i was driving homethat when im crusing lets say 3rd gear 3500rpm i pull out of gear into Nuetral and it takes like 5 secs for the idle to drop back down( like the IAC is stuck open) the car has like 2000 miles so theres no way its clogged.
any idias or comments?

RE: 91 Tune Problems
The lazy return to idle is a known issue with the car, it's actually a deliberate feature built into the tune to reduce emissions, believe it or not. You'll not get rid of that with or without a tune.
The throttle lag is a different thing, sounds like the tune hasn't got enough spark at the low end.
