just got the ms4 tuned and i am not happy! i have 853 heads and a ls1 intake. i know these are not the best heads and intake and trust me they arnt staying for long but a gain of 20 hp from this cam does not seem right.

dyno with stock cam. 340hp
dyno with ms4 cam. 363hp 343 tq

mods. Lt headers, z06 maf, slp lid, 4.11 gears,

 

its gotta be the ls1 intake, i dont have much experience in the internal mod department, but from all ive heard/read its gotta be the ls1 intake

 

Going to guess you're a 6spd? If so, yeah low numbers. Should be in the 380's at least.

 

#'s Are Low What Rpms Did Yo Uspin Till, Also What Valve Springs U Using, U Sure The Cam Saw Installed Proplerly? And Of Course Ls1 Intake Would Definately Hurt Est 15 Hp

 

not much info but I'll ASSume some shitty y-pipe, stock exhaust. Both are no no's and then throw in the fact that you're still on the stock ls1 intake? What did you expect buddy? A half *** setup and 400whp? Get real

 

i was not expecting 400 hp but at least 375-380 i have a off road y pipe and magnaflow exhaust. Im not an idiot, i just feel they are very low numbers for a 6 spd car. The car was taken up to 6800 and started falling off at 6500.

 

do you even have headers? i havent seen you mention that yet

 

i made 395/381 with my ms4 and worse heads i had 806's and a stock intake

 

Post the Dyno sheet so we can atleast see something cause those are the lowest numbers with MS4 thru M6 i've seen .

peace

 

yes this is thru pacesetter headers and 3 inch off road y pipe going to magnaflow exhaust. ill get the dyno graph asap.

 

Something is wrong. I made 385rwhp on stock exhaust manifolds ORY and borlamouth. Stock heads.

 

Is it even tuned? Car running properly before cam was put in?

 

Who tuned your car?

 

yes the car was running great before the cam. I the engine is building compression and is strong as hell, with only 79k miles. It feels about the same hp as it did before the cam. I had the same shop tune it that did my first tune.
I will not disclose who tuned it, but they are a very well known shop. Talked to jason@ tsp and he said he is willing to help me out and do a retune on my car, What a great guy!
sorry

 

You also have an 02 car, with an ls6 intake, better head design and better designed manifolds. Your comparison is nill.

 

Ls1 intakes don't hurt as much as most think. You should be higher with the ls1 intake. Hows fuel? Injectors? Spark? Many things to look at.

 

the engine is good! i checked everything before it was tuned and it is all up to par! I talked to jason@tsp and he i am going to take it to him to have it tuned.

 

Damn, crappy #s... I'm sure Jason, and trevor at tsp will hook you up though...

 

who tuned it in dallas??? only a few that can

 

definitely something wrong with those numbers, get a cutout and try dynoing it somewhere else.
