No gain unless boost is increased.
Boost may only be increased if no detonation is present.

what horsepower gain does one see going from non/adj to adj wastegate?
I want to see if someguys here can tell me how much power would be gained and how much time would be knocked off 1/4 mile times and mph gain at the track in general by going from a non-adjustable stock waste gate actuator with a reds93 chip and 94sunoco fuel and the basic mods i have written below to just removing the stock non-adjustable wastegate actuator and then installing an adjustable wastegate actuator and still use the same mods as i used before with the non-adjustable.?just curious if anyone has ever tested that swap.thanks

you can make your non-adj. to adjust using about $2.00 in parts from almost any hardware store. go here:

you will not gain much using pump gas only. 15 - 17 lbs. of boost is the max. (normally there is much detonation at this level) you want to try on pump gas. your biggest gain will be adjusting your boost up and using ONLY race gas or use pump and alchy...making sure you tune for NO detonation. yup
it was once an old wives tale that for every 1 lb. increase in boost you gain 10hp...but it does not apply to every car/combination. nono
i prefer to tune using 'seat of the pants' and a scanmaster...or go to test and tune and see how much you gain. headbang powersix

how many pounds safe boost can you run with just 94octane and a chip for pump gas only?NOSjohnWE4:

Also if i put race fuel in it at the track and raise boost i'll need a race chip,correct?
don't EVER count on someone's opinion, trust the ScanBastard...it works! however, when i have 94 in my car i think i get about 0.7 knock in 3rd gear at WOT and 17lbs., 1st and 2nd i think it hits about 2.0 - 3.0 due to the chip which is a Reds 94 chip for 50lb. injectors. in first gear i think my eyes saw it hit 21 lbs. once and 5.0 - 6.0, i then backed out of it not wanting to change H/G's. headbang
headbang
yup
Tanks guys,
It's just good reading knowledge for me to see what other guys are running on the street.Atleast it gives me some understanding of these cars.
