Ok, Can you give me a full numbers list that I would order from them? I want it still to be a daily driver and all I have valve train wise is 75# valvesprings so my rev limiter is 7500 whats the advantage of custom grind cams over stage 2 from zzp. I know we have talked before about this but a write up or a phone call 248 228 0721 about it would be greatly appreciated mr b

For your viewing pleasure
$50-100 part
Bolt on, change scaler to 4950 and adjust fuel trims via MAF/VE
9whp gain @ peak
4ftlbs gain @ peak
More power under the entire curve

how the heck do you get more power under a curve that reflects peak power?. Folks talk about this here like its pixie dust.
its bs.
peak torque and power was increased by an amount that is probably statistically as valid as the dyno variation due to ambient conditions.

My customer who has these cams on his TVS balt loves them to pieces

Fidget, stay away from the LS4 tb unless you have a high threshold for pain.

John,
Thank you, for both this and the advice you gave me on suspension modifications.

Does anyone know where I could get a Harrop sticker? I want to put it under my hood.

If you increase torque, hp follows suit. Over the entire powerband, it's evident torque increased; it's obvious past 5250 RPM.

All i know is i feel a lot more power with the ls4. My car responds alot faster and more direct.

My tuner before Rakes said he loved the LS4 (made a good gain) but driveability sucked

to properly do the ls4 tb, you need to change the pedal, and recall the backside of the ecm.

if your using 80's your gunna max them before redline
my 1000's on rsfs/dw300 are at 90%

i am sure this has been asked before but i dont want to read through 243 pages...

what all is needed to run a tvs with a 2.8? i have full boltons, and meth. main question is the fuel system. i currently have 60's with a 12 GPH meth nozzle using 50/50 mix. will i need a return style system, boost reference system, or anything like that?

If I were you just get 80's and be set

You don't need anything. I ran 60s last year on a 2.7" with a 14gph nozzle and my idc was shy of 80%

ok thanks
i have looked at these threads. i was more asking what you guys use i guess. i know i dont NEED a return system or anything but was more wondering if it would be beneficial or not.

reason i ask is because of this from ZZP on their boost reference system....

"
The PCM doesn't compensate for boost over 17.5psi (12psi on LE5), so the car begins to go lean after that because the PCM file does not see more boost above the 17.5psi. This is unless you raise fuel pressure the same amount as boost, which is exactly what our BRFPS does. You can try and tune around the 17.5+psi but it's guess work and a very poor solution."

ok so I installed my TVS 2.8 and 80s today and when I hit the dyno everything was great up until I get some mysterious Knock
now the plugs where changed a week before I shot down to the shop and it was holding full boost the entire time on the dyno
further more my tuner turned down the sensitivity on the knock sensor to practically nothing and in lower timing it was still around

so question is
Faulty knock sensor or something more serious?

Ive never had an issue with this place and have been going to him for a while now and its not his first tvs car he's tuned.

its the same man who tuned 07metalliacSC
