im trying to get at or above 400 whp, right now im at 380 with a ms4 cam and bolt ons, i have a set of stage 2.5 ported 241 heads in the shop right now gettin a valve job, do you think i will meet my mark? what do you think the gains will be? i will be back cutting the ex valves for a little more flow also. thanks -Jason

 

yep, i think you'll do about 420 whp with the heads on and a good tune to match the mods

Nice to see your in the 11s, im hoping for a similar setup with my car and use it as a daily driver. Im hoping for 12s this year, just put LS6 intake on, need to do EFIlive tune and putting LT and 3" true dual next week

 

my car is an a4, i wish i would be around 420 but that would be a HUGE gain im hopin for atleast over 400, BTW the 11.9 was without the car shifting into third, i had to completely letg out of it let it shift then get back in it.

 

what cam are u using? are u using 1.6 rockers? has the tranny been built up any?

 

I have a ms4 cam the trans has stall and shift kit not sure about the rockers

 

lol. ok i seen that but read a4 for some reason. has the computer been tuned? not sure how to test the 01 vss but it would be a good idea to look at it. also check the tps setting to make sure the tranny is getting the right thottle position. have u had it scanned for codes lately? a good scanner will let u test them or do a seach on the tps and vss tests and ill look for some links i may have real quick. 69 gave me one but dont remember what thread it was on.

 

Yeah. It has a speed density tune it has not throwing code it threw two shift soloniod b code and I replaced it twice

 

the tune may be the problem. u have a maf system so i would think a maf tune would be correct for a 01. a dino tune is the best way to go. pcmforless does a good job on the lt1, dont know about there ls1 tunes. the computer tells the trans when to shift so making sure its telling the trany what to do should be first.

 

the car was tuned on the dyno for the speed density the tuner lowered my shift points but still nothin, it still did it i want to go with mass air once the heads are on

 

have u tested the tps? vss? must be something in the tranny.
