Car won't boost past 23.8 psi, Dyno Results HTA Green
 

Just trying to get some more ideas as to why my car can't boost. I just had my new HTA Green installed along with injectors and a Grimmspeed EBCS and made a 317whp on a dyno dynamics with 1.0 correction. I was a bit dissappointed but the tuner couldn't get the car past 23.8 because it is pulling timing. I know dyno dynamics read lower than some mustang dynos but still....I thought maybe I had a bad tank of 93 but this same issue happened when I orginally had the car tuned for cams/bolt-ons. Tuner may have thought it has something to do with the knock sensor? Had the car checked for boost leaks, compression test, leak down test. Everything seemed fine.... I'm stumped. I have a 25psi WGA and I can't even get to 24psi. I know a lot of guys run 25-27psi on 93 without any problems. Any advice would greatly be appreciated....

mods in sig

send me a pm.. sounds like the car has excessive engine noise and both tuners were not experienced enough to know how to fix it. i deal with cars like this all the time.

as for 25 wga only doing 24psi.. its common depending on rod tension.

who tuned your car and who did the install, you may want to try another shop and tuner or do remote tuning? so if i am reading this correctly you had the same issue with boosting past 23.8 when you just had cams and bolt ons?

there you go tcomp is offering to help he should sort you out, good luck with your car. also i know a shop in nh with a very experiences evo mechanic (not a tuner though) if you want i can send you his contact info-

It may not be the shop's fault so out of respect for them I'll leave names out of it. The first shop who tuned the car with the cams/bolt-ons could not tune past 21-22psi, they orginally thought bad 93.

Ballistic Motorsports? If not shoot me the info. Thanks

It blow the EGR line off? Cam timing has been doublechecked and you know its not advanced a tooth or 2?

aaron

never mind saw it was not due to the turbo but the timing

hmm.. I don't know if the cam timing was checked. I will have to ask

Anyone check the wastegate arm if it's stuck?
I wish I can see your map.

Shoot Tscompusa a email he will help I am one of the cars that had excessive noise and he fixed it. I would def check the Timing and see if the gears might be off as it could cause a issue.

bump for charts

maybe i am reading the second chart incorrectly but is the afr going in to the mid 10's? that is pretty rich. there is also a spike there there that looks abnormal. i think once you get another tuner that knows what is going you will be good to go
