RICKLS on Feb/07/06 said:well in december i finished up my friends turbo ( 1994 ls) then tuned by jeff (evans tuning ) got it to 215 whp @6400 and 214 lb torque @5400 with 8psi . well now its febuary and he wants a little bit more , but really doesn't have the money to retune. my question is how much more boost would be safe without retuning ? maybe 2-3 psi ?
aalb1 on Feb/08/06 said:$200 for a retune assuming everything goes smooth... $100 for the first hour on the dyno... $100 for the second hour on the street.
What's his plan to get "a little bit more?" Swap out parts for more power? Or just up the boost?
