.justin. Posted September 7, 2005 Report Share Posted September 7, 2005 I've recently swapped in a 2-bar map sensor, re-scaled my VE table and all relavent tables to take this into account, and just about have the fueling dialed in. I'm thinking that since I can now set up the PCM to know when the truck is in boost, why not set up PE mode enable to be at 1psi when over a certain amount of throttle, say 50%. Does anyone see any drawback to doing this besides burning more fuel when this is occuring? I'm running a radix with 6lbs of boost right now...

zippy Posted September 7, 2005 Report Share Posted September 7, 2005 50% would actually be high for a radix setup. most often they are run around 40%. if you run a smaller pulley you can see 5psi at as low as 45-50% of throttle apply. Link to comment Share on other sites More sharing options...

Strangely though, the stock 5.3L radix tune that I have downloaded for comparison shows PE not kicking on til 90% throttle... I've had to basically build my radix tune from scratch from the stock SS bin, as I purchased a radix tune from a mail order tuner and it was not even close to what it was supposed to be...
